Kerberos authentication in cluster

[Jarosław Tabor]

Hello!

	I have hot-standby cluster with two servers: s1 and s2. This cluster
has also virtual ip address s3, assigned to current master.
	I can authenticate in s1 and s2 (postgres, gss) but when I'm trying to
authenticate in s3, I see:

duplicate GSS authentication request

I have created principal postgres/s3 and added it to keytabs on both
servers. What can be wrong ?

best regards
Jarek
