Update User_LDAP.php

[sretika]

userManager->getAttributes() could be returning empty values, which will give no result when used for searching. This patch will simply drop empty values in the $attrs before using it for searching.

As there is no feedback since a while I will close this ticket. If this is still a problem please feel free to reopen and explain what is happening in detail. Maybe together with some debug logs with the variable values.
