Using mail as login uid

[mxwendler]

We have very long email adresses, yet we use them as login names. When using mail adresses as uid, they are too long to fit into the php list user table row with 25 chars limited. So we switch to the ldap uid silently after login succeeeds.

Patch included. Works correctly so far, not extensively tested.
