Hi,
I'm testing Appian 7.3 with Jboss EAP 6.1 (java 1.7.21).
I updated spring-security-kerberos-core.jar (class: SunJaasKerberosTicketValidator) as suggested in this page:
jira.springsource.org/.../SES-119
but SSO with kerberos doesn't work.

I can see this error on server-log:

BadCredentialsException: Kerberos validation not succesfull
Caused by: java.security.PrivilegedActionException: GSSException: Failure unspecified at GSS-API level (Mechanism level: Specified version of key is not available (44))
Caused by: GSSException: Failure unspecified at GSS-API level (Mechanism level: Specified version of key is not available (44))
Caused by: KrbException: Specified version of key is not available (44)

thanks
Lorenzo...

Please ensure that your authentication files are properly configured: forum.appian.com/.../Authentication
Do you have a typo in how you've configured your LDAP server?

Hi Patty,

I use config files from my old appian version (7.2).
I updated in spring-security-07-portal-override.xml as suggested in migration doc.
I changed SpringSecurityBeanPostProcessor into BeanPostProcessorForPortalAuth.

Authentication with LDAP works fine.
only kerberos doesn't work.

Lorenzo, we are not really Kerberos experts and the error you are getting is not an Appian exception. I would suggest that you contact someone internally who has configured Kerberos SSO with their web app.
From experience, it seems to me that the version key is different in the keytab file and in the KDC (AD). I believe you can get the keytab version key using klist and the version key from AD using a network monitoring tool.
Good luck!

When you create your keytab did you specify the kvno as 0? I used the command ktab.exe -n 0 -a HTTP/USER PASSWORD -k appian.keytab. If the kvno for the ticket and for your keytab differ you will receive that error (after a quick googling)
