Can't connect to DB using GSS(Kerberos) auth

Before I did anything I checked the ticket cache:

*someuser(at)clienthost:~$ kinit -k -t drhouse.keytab -p
drhousesomeuser(at)clienthost:~$ klist -fTicket cache:
FILE:/tmp/krb5cc_20000_Z95lupDefault principal: drhouse(at)HOSPITAL(dot)DE
<drhouse(at)HOSPITAL(dot)DE>Valid starting Expires Service
principal13.05.2015 xx:xx:xx 13.05.2015 xx:xx:xx
krbtgt/HOSPITAL(dot)DE(at)HOSPITAL(dot)DE <HOSPITAL(dot)DE(at)HOSPITAL(dot)DE> renew until
14.05.2015 xx:xx:xx, Flags: FPRIA*

This is the corresponding keytab for drhouse:

*someuser(at)clienthost:~$ ktutil ktutil: read_kt drhouse.keytab ktutil:
listslot KVNO Principal---- ----
---------------------------------------------------------------------
1 5 drhouse(at)HOSPITAL(dot)DE <drhouse(at)HOSPITAL(dot)DE> 2
5 drhouse(at)HOSPITAL(dot)DE <drhouse(at)HOSPITAL(dot)DE> 3
5 drhouse(at)HOSPITAL(dot)DE <drhouse(at)HOSPITAL(dot)DE> 4
5 drhouse(at)HOSPITAL(dot)DE <drhouse(at)HOSPITAL(dot)DE>*
Now I launched eclipse from that shell and tried something like this:

*Properties connectionProps = new
Properties();connectionProps.setProperty("user",
"drhouse");connectionProps.setProperty("loglevel",
Integer.toString(org.postgresql.Driver.DEBUG));String databaseUrl = "jdbc:"
+ DBMS + "://" + HOST + "/" + DATABASE;connection =
DriverManager.getConnection(databaseUrl, connectionProps);*

The result was a failure to connect:

*xx:xx:xx.879 (1) PostgreSQL 9.2 JDBC3 (build 1002)xx:xx:xx.883 (1) Trying

On the server this looked like that:

*2015-05-13 xx:xx:xx CEST LOG: connection received: host=databasehostip

pg_hba.conf line 95: "host all all ne.tm.as.k/16 gss"*

BUT when I tried to connect using psql (from that very same shell):

*someuser(at)clienthost:/$ psql -U drhouse -h databasehost measurementspsql
(9.4.1, server 9.3.6)SSL connection (protocol: TLSv1.2, cipher:

Looking at the ticket cache:

*someuser(at)clienthost:~/eclipse$ klist -fTicket cache:
FILE:/tmp/krb5cc_20000_Z95lupDefault principal: drhouse(at)HOSPITAL(dot)DE

Any hint on what might be going wrong?

Thanks,
