when I create an user source with zman, I use the
modified sample UserSource.xml file. I leave the
authentication mechanisms setting as it is, i.e.
in the order 1)username/password 2) shared secret.
However, zcm11 put shared secret before username/password.
Because our tree does not have the schema extended
for shared secret, the login to zcm11 fail.

I have re-create the user source with the shared secret
option removed.
