Facing authentication failed after executing ensemble-add command on Fuse 6.1 with R2P3 patch.

Issue

• User applied the R2, and then R2P3 patch on top of it.
• After which, the command fabric:ensemble-add -f esf2 esf3 to extend the fabric ensemble fails.
• The only relevant ticket that user can find is https://issues.jboss.org/browse/FABRIC-1240.
• In the ticket above it says that it has been resolved. Is it confirm that the fix should be included in the R2P3 ? What could be the reason for this error?
• If user set the username/password to admin/admin and zookeeper password also to admin, ensemble-add runs just fine. However, if username/password is anything else, th error mentioned above occurs.
• Following exception message is received in logs.
