Browser debug error message. Looks like it's missing some key files that are not loaded by registration page only.  If message dialog was present we would have seen the exception there as well.

--- Additional comment from spinder on 2012-01-26 17:46:24 EST ---

A workaround is to first login with RHQ(non-LDAP) credentials first but that diminishes the purpose of LDAP integration.

However, the fix has been pushed to RHQ master with commit 42b9f09016e and will need to be cherry-picked to release/jon3.0.x branch.

Moving to ON_QA for verification, but needs to be QA'd in JON 3.0.1 as well.
