[Samba] Samba 3.0 and username map.

[Stef Bon]

Hello,

I'm using samba 2.2.8 for aprox 40 computers and about 200 users.
(no one has a computer for his own, so I'm using domainlogons and 
roamingprofiles) 

To map my (windows) users with unix accounts, I use a large (!) 
username map file. Apart from being large, I'm not happy with the way 
usernames can be added or modified.

My question is:
do I have to use the option username map still with samba 3.0 with LDAP???
I hope not. I've seen a thing as displayName in the sambaAccount. Is this a 
replacement for the username map??? 
(with ldap userdata can very easily modified. Thats why I am very happy with 
the ldapsam option)

Thanks,

Stef
