LDAP: error code 18 - Inappropriate Matching in iManager Simple Selection

In iManager 2.7.0, when using the Simple Selection Search you see two "E-mail address" selections, or what appears to be duplicates.  Which "E-mail address" you choose will determine if your search is successful or not.

In iManager 2.7.0, searching on E-mail address:
One search will actually search on "Internet E-mail address" nds attribute/ mail ldap attribute - this will succeed.
The other will search on "E-mail address" nds attribute / eMailAddress ldap attribute - this will fail.

This has been partially resolved in iManager 2.7.2.  In iManager 2.7.2, the "working" E-mail address search was renamed to the appropriate "Internet E-mail address" This one will succeed.  However the broken "E-Mail address" was left in the drop down for Simple Selection. This option should not be used, as it will fail.
