Hi all,

we’ve running some SLES11SP3-64 servers and using ActiveDirectory accounts for ssh logins.

Everything works fine with SP1, but after upgrading to SP2/3 we have the following effects:

  1. winbind crashes when an users tries to login and his account is locked:

  1. Before upgrading to SP2/3 the ssh login prompt shows some infos like “Your password will expire in x days”, “You need to change your password now” or “Your account has been locked. Please contact your system administrator”. Now it shows absolutly nothing then the normal password prompt again and again.

Any hints for this?

Thank you,
