uses of LDAP server

[Wong Shin Neng]

 Hello everybody,
 
 I just joined the list to seek opportunities in replacing our company's NT
server.  I am currently working on an integrated environment which I am
currently focusing on the uses of LDAP server to make life easier for
everyone in the workplace.
 
Could anyone tell me how well is SAMBA works with ldap server?  I heard it
is only at an experimental phase but is it safe to assume that it works?
Also, with a LDAP server, how much information can a Samba server rely on
the LDAP server?
 
 Thanks in advance....
