The community no longer maintains a specific release schedule or release
process for whitetank (we have moved on to corosync). This is why it is
"unmaintained".
Red Hat, on the other hand, absolutely supports whitetank in their
products for the lifetime of RHEL5. This mailing list is not the
appropriate place to discuss vendor specific products. Please contact
your vendor for support questions.

We added support to corosync to do this called "uidgid.d" directory.
But this is not available in openais.
