Thanks Tony, that really helped! :)

By syntax i mean something like this (openLDAP schema...but i need a 
version for sun Directory Server 5.2).....

attributeTypes: ( NAME 'sambaLMPassword' DESC 
'LanManager Password' EQUALITY caseIgnoreIA5Match S
defined' )

....i dont have an attribute called sambaSIDList...

By the way what is GQ? i have created my own perl scripts to do the 
things i want, have made into a nice webpage for our admin team to use! :)
