Subject: [PATCH 13/18] Revert "LDAP/IPA: add local email address to aliases"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This reverts commit 9a310913d696d190db14c625080678db853a33fd.

Storing the e-mail address as a nameAlias was a performance optimization
to avoid having to fall back to the UPN lookup, but had the disadvantage
of returning multiple results for cases where an e-mail address is the
same as a user's fully qualified name.

Since the e-mail lookups would still work without this optimization,
just after one more lookup, let's revert the patch.
