question about pgAdmin on windows 7 client using a MIT Kerberos enabled Postgresql server

Hello,

I got the following issue:

I am using the latest pgAdmin on OS X (El Capitan) and used the version included in the latest Postgres package from enterpriseDB: http://www.enterprisedb.com/products-services-training/pgdownload (64 bit version)

We are using kerberos auth on our postgresql servers using MIT kerberos.
For OS X this works without an issue using your received kerberos ticket.
For Windows 7 the same version does not seem to work and gives an error:

SSPI continuation error: No credentials are available in the security package

We are using MIT Kerberos Ticket Manager (kfw) and requesting a kerberos ticket from the MIT Kerberos server works fine.
I also try to set it to GSSAPI and switched to SSPI using the system environment variables:

setx PGGSSLIB sspi /M
setx PGKRBSRVNAME postgres /M

I tried these settings reading a former issue: http://grokbase.com/t/postgresql/pgsql-admin/089as0k65k/postgres-8-3-3-gssapi-and-windows-xp but with no luck.

So using the same pgAdmin version on OS X and using it’s native kerberos client works perfect with pgAdmin, using the MIT kerberos client on Windows and using the same pgAdmin version gives this error.

Does anyone know how I can solve it or can I debug (aka strace) the pgAdmin.exe process on the windows client(I tried using ps monitor) so I can perhaps see what is going wrong?

Thanks for any help.

Cheers,

Michiel
