Verified with uidgid-parse.sh:

FAIL on corosync-1.4.1-15.el6.x86_64 (RHEL6.4)
PASS on corosync-1.4.1-17.el6.x86_64 (RHEL6.5)
Sep 11 18:10:06 virt-014 corosync[5211]:   [corosy] The 'nonexistinguid' user is not found in /etc/passwd, please read the documentation.
Sep 11 18:10:06 virt-014 corosync[5211]:   [MAIN  ] Corosync Cluster Engine exiting with status 1 at mainconfig.c:622.

Just a question: does it really check only /etc/passwd or is it also friendly to other system user entries (like ldap users) and the message is slightly misleading?
Comment 8 Jan Friesse 2013-09-12 04:15:58 EDT
It calls getpwnam_r, so second option is true.
