I also would like to see patches for the linux/mono version. This is unacceptable how long between updates.

Everyone, Update to 6.6, for linux it has active directory as an option, i've not yet had a chance to set it up. Not sure if it's just LDAP, but the fields available are 

DirectoryServerOverride
ServiceUserNameOverride
ServicePasswordOverride


No reason to not support this when it is supported on windows.
