Patch to eliminate extra bind in LDAP code none

Description Ian McLeod 2009-11-16 11:43:49 UTC 
Description of problem:

The existing autofs packages in RHEL5 fail to interoperate with the Sun LDAP server.  As part of a customer interaction outside of this BZ, Ian Kent has identified the root cause.  From Ian's attached patch:

"During the sasl authentication (and possible authentication method
selection) we establish a connection and then dispose of it and then
bind again. This is a little inefficient but some servers don't like
to bind again using the same LDAP handle and authentication fails
when it should succeed. We should use the authentication connection
once we get it and not perform another re-connect later. "

This patch was successfully tested against a Sun LDAP server on a customer site.  It resolves the issue.
