commit 3c3e0dd3dbca52c6edb5ce86d7de2ab09556e838
Author: Christine Caulfield <ccaulfie@redhat.com>

[CMAN] fix cman_tool join -X

Even when state with cman_tool -X, the preconfig stage tried to lookup
the node in the objdb (which is empty!) and fails if it was not found.

The "aisexec" object did not exist so the username was not stored.
