Hello,
I have a number of machines running Ubuntu. On one machine I have the problem that the "su"-command does not work as expected.
When login as the local user "myroot", I can execute "sudo su -" and switch to root-user. Trying executing "su bjoern" (a valid user in an LDAP directory), I get the error message "setgid: Die Operation ist nicht erlaubt".
When login as the user "bjoern", I can login. When I try to execute "su myroot", I get the error message "su: Fehler bei Authentifizierung". I am quite sure that I have given the correct password.
As root, I can do both "su bjoern" and "su myroot" without problem.
What could be the problem?
