Indeed, I mis-spoke. I am aware of the issue. I normally upgrade the EL
machines to whatever the latest version of samba is. There are simply too
many features missing from the versions supplied with RHEL. Hopefully EL5
will have something near current. I was not aware of the kde-redhat samba.
I will have to look at it.

OK, so we strip out the above attributes at import time but does FDS then
recreate them? My memory is telling me they are part of the required attributes
in the schema but I could be wrong.

Thanks for the help.
