After an upgrade of Access Gateway, Kerberos authentication is failing and forms auth is being used.
In the smps.log,
"Failed to initialize authentication scheme 'internal-SPS-kerberos-AuthScheme'"
In the smtracedefault.log,
"Kerberos Login Failed: Pre-authentication failed: Key table file '/etc/krb5.keytab' not found"
Release : 12.8
The policy server is not able to find the keytab file.
1. The file exists in the path.
2. Permissions on the file are correct for the account running the policy server.
3. The environment pathing is correct so the file can be located by the service.
