sshd/PAM: getgrgid failed
I guess this is an upstream bug in either PAM or OpenSSH. I saw this on SLES 10 SP2, OpenSSH 4.2p1, PAM 0.99.6.3.
Here, we use pam_listfile.so in /etc/pam.d/common-auth to restrict access based on groups. For some LDAP GIDs, we are getting this error while users with a different primary GID are able to login:
myhost sshd[PID]: error: PAM: Error in service module for youruser from 192.168.0.227myhost sshd[PID]: pam_listfile (sshd:auth): getgrgid(1111) failedI changed 'onerr=fail' to 'onerr=succeed' in /etc/pam.d/common-auth and it solved the problem - the PAM error appears, but the login process can go on.
auth required pam_listfile.so onerr=succeed item=group sense=allow file=/etc/allow.grp
