Hello,

I am running sssd on RHEL-6 with AD and recently found out, that I can no longer authenticate via ssh.
The message is:
pam_krb5[27045]: TGT failed verification using keytab and key for 'nfs/draco.prague.s3group.com@DUBLIN.AD.S3GROUP.COM': Wrong principal in request

My krb5.keytab file has been created using Samba with "net ads join".
I can still run 'kinit <username>' to obtain a TGT.

Does anyone know what is going on here? Why is sshd verifying the TGT via just the nfs/ service principal?

Sorry for a bit off-topic question, but I hoped someone in this list might point me in the right direction.

Note that with:
kinit -S nfs/draco.prague.s3group.com@DUBLIN.AD.S3GROUP.COM ondrejv

I am able to successfully obtain the nfs/ principal - so it looks like a bug in pam_krb5, right?

Many thanks,
Ondrej
