I was looking in the wrong direction, because of kerberos errors, after upgrading from oneiric to precise.
This bug is not related to kerberos, but to OpenLDAP. OpenLDAP has two configuration files for authenticating against a ldap-server: /etc/ldap/ldap.conf -- used by nsswitch /etc/ldap.conf -- used by other tools including kerberos, if kerberos data is stored in ldap. Both of these files are overwritten by "do-release-upgrade -d", breaking the connection to your ldap-server. In tune kerberos can't read it's database (stored in ldap) any more, while the connection is not broken, because /etc/krb5.conf holds the necessary information. But Informations for authenticating kerberos against ldap are stored in /etc/ldap/ldap.conf and these are lost. The error messages kerberos exausts lead in a false direction. Resoring the files /etc/ldap/ldap.conf and /etc/ldap.conf solves the problem. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to krb5 in Ubuntu. https://bugs.launchpad.net/bugs/971028 Title: kerberos auth doesn't work because of kerberos server not found To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/krb5/+bug/971028/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
