The spn is POSTGRES/pglgisprtd001.sempra.com@CORP.SE.SEMPRA.COM, as I set up different servers, the server in the spn changes of course. The server name resolves, and if I do a klist on the keytab the realm matches.
I am thinking that it has to do with our “vas” & “vasd” systems and how it is configured. But I can’t really say.

Subject: Re: [ADMIN] GSSAPI / Kerberos Authentication
I was just looking at the Kerberos support. Is your server principal postgres/x.y.z@REALM, where x.y.z is the DNS name for your server? It probably won't affect you but think it needs to be POSTGRES/x.y.z@REALM for windows networks.
I'll have to check my notes for more details, e.g., I'm 99% sure it's 'postgres' and not 'postgresql'.
I know you need to use password authentication from the client - and the username has to be simple (bob@REALM, not bob/postgres@REALM). I'll be submitting a patch to support a keytab file and compound principals when I have some free time.

I am currently trying to configure a Centos6.x – postgresql-9.3 server to authenticate using gssapi. I have several servers I have already configured and are working (a combination of Oracle Linux and Centos, all 6.x series with 9.2,3 or 4). Our company use vas for an interface to Kerberos, The errors I am getting are as follows:
[sweingar@pglgisprtd001 ~]$ psql -hpglgisprtd001 -dpostgres
psql: GSSAPI continuation error: Unspecified GSS failure. Minor code may provide more information
GSSAPI continuation error: Server not found in Kerberos database
or from a windows client
C:\Users\sweingar>psql -hpglgisprtd001.sempra.com -Usweingar
psql: SSPI continuation error: The specified target is unknown or unreachable
(80090303)
I see nothing worthwhile in the postgresql log, nor in /var/log/messages. I have verified the dns record to my kdc works (or at least I can ping), I am sort of at a loss of where to look next.
