[rt-users] Updated LDAP-SMB overlay

[Russell Mosemann]

I have updated the LDAP overlay from the Contributions section and added a
few features.  Here is an excerpt from the README.

Main Features and Changes
* Fixed some bugs and rearranged code.
* Added authentication and auto account creation through SMB.
* Order and choice of authentication methods may be specified.
* Home/ticket page default refresh intervals may be specified.

The overlay is available at
http://www.mosemann.com/software/LDAPSMB1.1_RT3.tar.gz

The file may be placed in the Contributions section, if suitable.
