Kerberos error in post processing: Kerberos preauthentication failed

[Ambati, Satyanand]

Hi Team,

We are getting "Kerberos preauthentication failed"


1) mpgw (kerdDemo_MPG): ldap authentication succeeded with (http-basic-auth, username='xxxxx' password='xxxxx'configured-realm='login' )


2) Ticket cache miss; fetching ticket for client 'xxxxx at xxxxx' and server 'ldap/xxxxxxxx at xxxxx'


3) Error :mpgw (kerdDemo_MPG): Kerberos preauthentication failed


4) Kerberos error in post processing: Kerberos preauthentication failed


Event Code 0x81400023 - 
The Kerberos KDC rejected the preauthentication in our service ticket request.

Suggestion:
Check that the client keytab is the right keytab for the client. If the KDC is Microsoft Active Directory, make sure that you are using the latest ktpass utility to extract the client keytab. See MS Knowledge Base Article #919557 regarding buggy versions of ktpass that can cause this error.


Any help is greatly appreciated.


Thank you,

Does a kerberos database already exist on the machine?
strace (or equivalent) should make it quite clear what path is returning 
ENOENT...
