• DMVPN and active directory (logon)

  Hi all

  We have a DMVPN configuration between a few sites and everything seems fine, except that the logons through the VPN for a new domain active directory are very slow (10-15 minutes). I believe that the problem may be with the fragmentation of tunnel and packages such as AD is configured correctly.

  I am looking for some recommendations or advice on the MTU and TCP MSS settings see if it solves the problem.

  both the hub and the spokes are currently with the following settings MTU and MSS (ive removed some irrelevant information) Tunnel0 was originally a mtu of 1440 but if whatever it is 1400 is even worse.

  Thank you

  Darren,

  In general the prolem is due to Kerberos on UDP traffic.

  There are several ways you can solve the problem:

  (1) transition to Kerberos over TCP. (suggested)

  (2) setting the MSS on the interface of tunnel not on telephone transmitter (recommended)

  (3) allowing the PMTUD tunnel (strongly recommended).

• VSphere 5.5 and active directory

  Hello

  I'm having a problem trying to set up a new device Center 5.5 use AD permissions. My ad is 2012, I gave the host in which the vc unit sits on a COMPLETE domain name and it is joined to the domain, then, I'm going to the VC unit and join it to AD that she is successful. When I go to add permissions the ad domain is here not only local and sphere.local appears.

  When I look in the AD, I noticed that the host and the VC have not computer accounts even if they seem to be joined to the domain successfully.

  Any ideas would be appreciated.

• Is there another solution to integrate NAC Appliance and Active Directory on Windows 2008 64 bit

  I'm trying to integrate a device of the NAC solution in a network where all domian servers and application servers are Windows 2008 64-bit.

  Could someone help me to confirm if Active Directory (AD) on Windows 2008 is not taken in charge and tell me what alternatives exist to authenticate users who consider that it is not possible to make any changes on the server. They will continue to be Windows 2008 64 bit.

  The original idea was to use AD SSO to authenticate users, but I read that it is not supported on Windows 2008 64 bit.

  I'd appreciate any help or suggestions.

  Concerning

  Arturo Monroy

  Arturo,

  You can use LDAP. Configure an LDAP authentication provider and have your customers to provide their credentials.

  It will not however a single code access scenario. They would have to enter their credentials again on the NAC agent.

  Support for 64 - bit is on its way and will be out in the new versions soon.

• ISE personas and Active directory

  Hello everyone,

  just a question...

  Which character has need of more bandwidth with Active Directory?

  Assuming that I have admin / - fire guard - political service monitor

  wich side place AD? (cause of firewall bandwidth limits)?

  Thanks in advance for your answer

  The node primary admin and the political service nodes. All nodes join the AD, but when you create groups in AD and build your policies which is made from the node of the main admin, PSN nodes are responsible for enforcing those policies. It is my personal opinion.

  Thank you

• Continuation with VIO and Active Directory reference error

  While deploying the instance OpenStack de VIO, I get the following error message when checking the parameters of authentication source:

  Cannot find the specified user (Group). Details: The LDAP search request failed. Further reference

  This seems to be a problem, I met several times, where AD would send a reference instead of the response that the client must follow. But I don't see any option to allow removal with Active Directory. Is there a way around this?

  Concerning

  Gerald

  I found a work around for the problem:

  The query is successful when you use the ports for the Active Directory Global catalog.

  The ports are:

  • 3268 (without encryption)

  or

  • 3269 (with SSL)

  Disadvantage: You can't just use your do domain name address all the domain controller, you must specify one with its host name.

• ESX and Active Directory

  Hello

  I have a succession of VMware ESX ESX 3.5 70 servers and I want to be able to manage better the connection, I am familiar with the addition of the accounts of users and groups by VI or by using a command. What I want to do is if possible to create different groups and modify it permissions on each host via a script, and then if possible to add users to the same group in Active Directory and user management centrally via AD. If this is not possible, I would like to script adding user accounts and change the permissions of the user. I like to keep as manageable as possible to control the user accounts and permissions, more than 70 servers may prove to be multitasking.

  Thanks in advance

  This is the best post I've seen on this task.

• Cloning and Active Directory

  I just came across trouble cloning a win2003 server in Active Direcory. Once I renamed the cloned that he renamed the initial account of the server in Active Directory, so I could not connect to the source server over.

  I've always had to run newsid.exe after a clone or the Configuration Wizard can do?

  If you use the feature to customize comments, it will generate a new SID for the clone if you ask.

  I misread your post origionally and was about to recoment that you clone servers Active Directory (for example, domain controllers)

• Problem of ESXi 5.5 and RAID

  So I have an ESXi host and RAID problem with a motherboard for Intel Server S1200V3RP. Basically, the problem is that the 5.5 ESXi host is not recognizing the RAID array set up with the utility integrated. See the images below for what I mean.

  I did some research and my research has pointed out to me the possibility that this on the Intel Server raid controller is not actually a hardware controller but a piece of software built using the computer as controller. My research basically tells me that ESXi is super picky and don't play well with fake RAID. Although I may be wrong on this subject the behaviour of ESXi and each site Web I found says that this may be the case. I tried integrating storage and RAID drivers in the iso ESXi, I tried to update the BIOS chipset with the deployment server disk, and the management and I tried a USB installation with the drivers but nothing seems to solve this problem.

  Since ESXi does not the table as something other than dedicated disks, I tried an inventive work around by choosing the AHCI BIOS and install ESXi 5.5 mode host on a dedicated disk (volume 0). Then I switched back to RAID and used the Intel Rapid Storage Management utility to configure a RAID5 to three remaining disks. It seems to work very well and I was able to access the vsphere ESXi environment. However I couldn't see the RAID volume again on vsphere storage.

  I've plotted a plan where I could load the drives as individual data on the host and virtual server stores use the disk management utility or another program for RAID 3 hard drives together so that they appear as a single volume. However when I booted the system upward it appeared that the integrity of the RAID5 degraded after the addition of each drive separately (probably because he had to load a VMFS on each disc, thereby breaking the table). So this probably won't work (and even if it's possible, it's probably unnecessarily complex).

  So yes, I don't have really a clear idea of the place where to go to get the RAID controller integrated to be read by ESXi. I was told that there may be compatibility issues between VMware and my Intel server model, but I checked and its on its list of approved so compatibility it couldn't be her. I guess I could just stick with dedicated drives and load the HARD drives as data stores, and then use software RAID across virtual machines - but I am concerned about the way in which redundancy will include when we drive finally fails (could I just Exchange on as a hardware raid?). I always thought that software RAID (especially on windows server disk management) smb read and write speed is terrible compared to hardware RAID.

  Anyone know a solution to this problem or where I could go from here?

  I did some research and my research has pointed out to me the possibility that this on the Intel Server raid controller is not actually a hardware controller but a piece of software built using the computer as controller. My research basically tells me that ESXi is super picky and don't play well with fake RAID.

  ESXi is not 'super picky' here. This kind of fake-RAIDs that are so common on desktop PC motherboards and entry-level rely on specific drivers provided by the hardware vendor to work really. And suppliers basically only provide Windows drivers in the first place. Any other non-OS Windows would be faced with the same question. Try installing a Linux and that you will not see your RAID volume either.

  Yes, your motherboard does not use a real independent of hardware RAID but a cheap RAID/fake-software controller. See the Intel website:

• WLC4402, SSC 4.0, EAP FAST with ACS 4.1.23 and Active Directory

  Hi all

  I have a problem where my client software SSC (Cisco Secure Services)-wireless on laptops don't will authenticate the windows domain users if they enter the user name and passwords manually. The unique signature feature will not work. I am using EAP-FAST. It is an ACS appliance based server that I restored from the recovery CD.

  When I look at the failure of authentication request I can see that she is trying to send [email protected] / * / during an attempt to SSO on. The log shows that it is a bad user name or password. Note that the end of the domain name is missing.

  I can see the authentication attempt in the log of the remote agent (CSWINagent.log) on the domain controller, so I don't know that it sends the connection request to the domain controller. The Remote Agent is the same version as the ACS server. When I authenticate successfully (manually) it sends not the domain part of the user.

  This is a new installation. Initially, I had 2 remote agents, both on the service domain controllers has been run under an account with sufficient privileges windows domain administrator. After a planned turn off weekend windows authentication has stopped working completely. I found a post in this forum that says to use the local system to start the remote agent service. This led windows authentication to life, but now I have this problem. I don't know that until I changed it the manual connection is also required in domain (IE user domain\username). I can't be sure that this is the case!

  Can anyone help me to get windows AD to accept these credentials, because they are sent to the client connection? Otherwise if I can make it work with the user account, he worked with initially then that would be great.

  Thank you very much

  As you mentioned that SSC transmits the username "[email protected] / * /" in SSO.

  Is what I think for the moment, to use the feature of Distribution of Proxy on ACS.

  that is, demand to come as it is "[email protected] / * /', let's make ACS Stip off"@domaine"and"username"to RA for AD verification."

  http://www.Cisco.com/en/us/docs/net_mgmt/cisco_secure_access_control_server_for_windows/4.1/user/NetCfg.html#wp342969

  After stripping '@domaine' send the request back to the ACS it itself, i.e. in the column forward to, ensure that we have input of the ACS.

  And let me know if it works for you?

  Kind regards

• Unable to add agents to Exchange and active directory fglam

  I'm having issues getting the announcement and exchanging cartridges to add new agents. The Exchange and the advertising agent package has been properly deployed. However, when you try to add and configure new agents, errors will prevent the installation of the future.

  I get the following error whenever I try to install Exchange followed 5.6.3.1 agent version.

  "Access error to the mydomain.com with the supplied user name and password: javax.naming.CommunicationException: mydomain.com:389 [root exception is java.net.ConnectException: Connection timed out: connect].

  I confirmed usernames are correct and work passwords and user account has access to connect to Exchange and to perform operations.

  I opened all the ports required by the installation docs and Foglight requirements. The network between the FMS and fglam boxes and Exchange are on opposite sides of a firewall.

  I fear that port 389 is not yet open, and I was wondering if anyone has experience with the exchange connection and agents of the AD through the firewall. If so, what has been your experience?

  Thank you

  A number of things I've noticed in the past:

  1 make sure that the machine/machine virtual fglam is running have enough memory for the fglam create agents.

  2. for AD and exchange please check the release notes for these agents, especially when AD/Exchange running on Windows 2008 R2, there are a lot of prerequisites to allow agents to collect data.

  3. If you did the pre requirements, I saw cases where it took a long time for the system to respond. In these cases what I usually do, is go to administration > dashboard status agent and change the properties of the agents. I give the connection timeout, a very high value (typically, I add a few zeros to the number that is there).

  In addition, if you check the edocs you will see both for AD and Exchange there is a troubleshooting section and a guide to diagnosis remotely.

• Problems with ESXi 5.1 and 5.0 in a WS9 EFI - VM

  Hello Jim

  I'm testing ESXi LiveCDs to version 5.0 and 5.1.
  In the LiveCD, I use a state.tgz to enable SSH and ESXi-shell and set a password.
  The LiveCD works fine if I use them on WS 9 virtual machines with firmware = "bios".

  If I try the same CD in a virtual machine with the firmware = "efi" I am not able to get the network began.
  If I built a CD that does not use the state.tgz the network is fine.

  For now, I'm building the CD with different boot.cfgs for MBR and boot EFI.
  But I prefer to use the boot.cfg even with a state.tgz that works for both scenarios.

  I enclose the EFI - VM's vmx file and the state.tgz file.

  Great!

• Snapshots and Active Directory member servers

  I work in a test environment and install new application relies on our servers windows 2003 comments at least daily. There are 3 guests for each application system. We use snapshots on theses customers, who are members of domain servers, so that we install each generation of the same question every time.

  We found that we also had to remove each Member of the AD domain server and add it in each time. This allows our application to work, but it adds a bit of time for the installation of generation process.

  We never instant domain controllers.

  I was wondering if anyone has another way to remove/add member servers of the field without going through the GUI and all required reboots.

  The best way to solve this problem is to disable machine account password changes.
