Kerberos authentication to cluster

[jarek]

Hello!

I have two servers (s1, s2) working as hot-standby cluster with virtual
ip address (s3), which is assigned to current master.
I have created host/s3 user in kadmin and added it to keytabs on both
servers, but when I'm trying to authenticate to s3, I see:

duplicate GSS authentication request

What is wrong ? How such scenario should be deployed ?

best regards
Jarek
