Comment 4 for bug 1438856

The problem is due to metadata no longer selectable by all users. When an MXOSRVR is returned to the pool, the context is the ast user to logon successfully. If this is not DB__ROOT (or a user with SELECT privilege on the AUTHS table), authentication fails ith a privilege error, which is translated to internal error for the user.

The long term fix is for MXOSRVR to have a DB__ROOT context it can switch to while in the pool. The short term fix is to enable internal query during authentication to allow the select from the AUTHS table to succeed.
