Strange PAM message

[Frederic Praca]

Hello guys,
has anyone got these messages :
Oct 16 11:24:54 coruscant sshd[2690]: User root from 89.211.244.245 not
allowed because none of user's groups are listed in AllowGroups
Oct 16 11:24:55 coruscant sshd[2690]: fatal: Internal error: PAM auth
succeeded when it should have failed

FYI, I have a sshd server prohibiting root logins so the second log
made me think about a possible break-in attempt and maybe a succeeding
one :-(

Any idea about what these messages mean ?

Fred
