Kerberos authentication problem

• Kerberos authentication and use the KTPASS tool

  I work in support to a network analysis software company.  We have the ability to use Kerberos authentication for our product.  Recently, we found that when you generate the keytab file using ktpass on a Windows Server 2003 or 2008, it is a step backwards in the process.  Eventually do you run the ktpass twice to get the keytab file good.

  Our external authentication module is software that uses Kerberos authentication and then he puts it on a remote client computer to access our software. We configure our Kerberos application and then read from the file keytab generated on a Windows Server 2003 or 2008 domain controller by using Kerberos V5 found in the AD domain controllers.

  When you run the ktpass tool, you must submit the username and password to generate the keytab file.  When it is generated, there is a generated KVNO number / incremented in the keytab file.  But it writes the file first and then updates the KVNO + 1 number in the actual key stored in AD.  If your keytab file is always number 1 behind what is actually stored in AD!

  We can fix it by running ktpass once,

  Examine the properties for the KVNO number in the last keytab file

  Re-run the ktpass, but number KVNO + 1

  The keytab file is generated, AD wrote the new KVNO + 1 number in AD

  But now our keytab file matches KVNO number generated by AD

  We lose a step in the ktpass tool?

  is there a way to see what the current number of KVNO is set in AD

  We have tested extensively with Windows 2003 and Windows 2008 R2 domain controllers

  The guests were the two Windows 7 Prof 64 bit

  Was just curious if anyone has had this experience?

  Thanks in advance,

• Kerberos authentication PeopleCode works do not (FUNCLIB_LDAP. LDAPAUTH. FieldDefault.KRB_AUTHENTICATION)

  Hello

  I try to enable Kerberos authentication on our PeopleSoft (8.53.24 tools) system and have problems with authentication peoplecode. More precisely, the function KRB_AUTHENTICATION() in FUNCLIB_LDAP. LDAPAUTH. FieldDefault(). I've set up according to the instructions contained in PeopleBooks. The web server accepts a valid Kerberos token and runs the correct PeopleCode. Successfully, it retrieves the username since the token, but when it instantiates the class KerberosSSOValidator and calls the validate() method, it will return a "NULL" string for the & variable validUserName, which actually fail subsequent evaluation of IF. See below and note the code highlighted in red indicating where my problem lies:

  If Len (& userName) > 0 Then

  & krbToken = Substring (& krbToken, 11, Len(&krbToken) + 1);

  & validator = GetJavaClass("com.peoplesoft.pt.desktopsso.kerberos.KerberosSSOValidator").getInstance ();

  Local chain & validUserName = & validator.validate (& krbToken);

  If & validUserName <>'NULL' And

  & princName = & validUserName then

  SetAuthenticationResult (True, Upper (and username), "", False);

  & authMethod = "KRB";

  End - If;

  
  

       End - If;

  I added a few statements to insert the values of the various values that are at play in this block of code and I can see that before you call $ () validator.validate & userName correctly holds the user ID who came through in the Kerberos token. I also confirmed that the call to instantiate KerberosSSOValidator not returns a null object (if it was that the later line would fail anyway). Yet validate() always returns a string "NULL". Also, if I replace the call to validate and the hardcode & the validUserName = "< username >", it connect me (or someone) as my ID if they try and hit a page of PeopleSoft.

  Someone else knows this error? Please respond with any information specific to this code, and not with Oracle instructions on setting up Kerberos authentication. I follow the steps.

  Finally, we have solved this problem. The problem is that when a keytab file has been generated, the parameter -mapuser was absent from the ktpass command. Thus the SPN has not correctly mapped to the service account we created for this feature.

• Authentication problem when you try to connect

  I have a Linksys router. Connected WN2000RPT as described in the instructions of Netgear. Everything went through the lights very well, good, EXT appears on the scan available networks, etc. Tried to connect a Smart TV Vizio and burn TV Amazon tablet Asus. All 3 devices show... EXT with a strong signal. However, each device does not, connect with an error message 'Authentication problem' or simply 'cannot connect."

  My router is connected using personal safety ' WPA2/WPA mixed. " When you configure the wifi extender, I said to use the same SSID and the security that the router setting. Online reading on the settings available on the WN2000 and decided that the problem was perhaps a "lag" in the security implementation because WN2000 is not the same as available router setting. Do you have a factory reset on extension and returned to through the procedure, only not selected use the same level of security as a router, but manually selected WPA/PSK (AES) for the Extender. Same exact error of my devices as before.

  I thought that maybe by using the security settings of the router it was to spoil the Extender because they do not have the same settings available. But perhaps using different parameters (when the Extender receives the signal from the router, but perhaps on a "pass-through" only basis?) problems as well?

  So, can someone tell me if there is a way to get my devices to connect to the Extender, or this is always going to be a problem because the router has a security setting, and if I manually set the security OR say scope to use the same security settings, it will not work because the two units are not compatible? I'm doing something wrong? Any ideas? Thank you!

  Hello RealisticDave

  Did you have a different SSID on the router and not the same as routers SSID?

• Need to implement the alternative login if Kerberos authentication fails.

  Need to implement the alternative login if Kerberos authentication fails.

  In our case, we are sure that Kerberos will fail because we allow agencies 'B' to access this application of reliable source.

  Kerberos fails and the application should display the name of user and password page and then authenticate.

  In the web.xml file changed auth method basic with Kerberos, set up successfully.

  'A' agency users can make successful Kerberos SSO. But when an agency "B" SSO access will fail with 401 and the application appears pop base with the name of user and password fields.

  When the user provides the details and present application returns 401 again. not able to go beyond these steps.

  Please provide your inputs.

  can you please enable security ATN debug and share the newspapers?

  Who will be telll us why the authentication will fail.

  Replace the CLIENT-CERT, BASIC authentication method in the web.xml and try.

  What is the default authenticator control indicator? I think that its just / optional.

  Hi friends,

  Hi, Saro,

  Connection to studio ODI as a SUPERVISOR user. Go to ODI--> Switch authentication mode--> give your contact information to ODIREPO and sign in.

  You will get the message properly connected. Click the Security tab. try to connect as a SUPERVISOR. Once the connection is successful. Go to the user of the cprresponding (dev_biadmin) account and change the password.

  Logout and go to ODI--> switch authentication mode. Give the details. It will change external authentication. Now you should be able to log in as dev_biadmin.

  Hope this will solve your problem...

  Kind regards

• Active Directory kerberos authentication ticket control

  Hello

  Customer asked if Active Directory cartridge has the ability to control errors in Kerberos authentication ticket? For example when the user has too many groups in his account AD and the Kerberos ticket is larger at all an ad.

  Thank you

  Hi Miska,

  A search in eDocs reveals that there is Directory Services Performance view of health that includes:

  Kerberos Authentications. This counter displays the rate at which clients are using a Kerberos ticket to authenticate to the DC.     Authentication Requests. This graph displays the number of times per second that clients use a Kerberos ticket to authenticate to the DC.
  

  These parameters are evaluated for the Rule of authentication Kerberos LDAP:

  Purpose This rule monitors the number of times per second that clients use a Kerberos ticket to authenticate to a DC. An upward trend may result in issues with LDAP-dependent services
  

  These references appear to be the closest thing "the ability to control the Kerberos authentication ticket errors."

  What is your user directory? AD

  You try to authenticate the users connected to the windows domain already?

  If the answer to those is yes then configure authentication Windows integrated and by default it will use Kerberos

  If this is what you need then let us know and I can give you some advice
