GKSudo + Kerb5, not showing password dialog

[Bastian Pflieger]

Hi

I am not sure if this is the right list to ask, but I don't know where 
else to ask.

I recently upgraded my network to use kerberos 5. During that process I 
replaced the pam_unix auth modul with pam_krb5. But since that, when I 
execute the gksudo the gksudo process hangs (gksudo + 2 sudo childs). It 
shows no enter password dialog.  All other auth apps are working (login, 
gdm, plain sudo etc). Is this a known problem or is there anything 
special to do?

Thank you for any advice.

Regards
Bastian
