Hi Jochen,

	on another security issue, how do your samba servers authenticate to your idmap ldap backend server? Do you have to allow anonymous write access? I certinly would feel this was poor if that's the case.
And you have listed only one LDAP server as your backend, will this not cause a big problem if it falls over? Can you specify more than one LDAP backend server?

	thanks Andy Smith.

If you want see what *everybody* can see try an "ldapsearch -x -b
"dc=MYDOMAIN,dc=DE" -h adscontroller -p 389" on a UNIX-Box.

I've attcht my own configuration I use on an ADS Domain Member. The
Winbind-Stuff comes from an other LDAP-Server and has no relation to the
ADS-LDAP. If you don't use winbind you won't need the winbind section.
You should first do the "kinit Administrator at REALM" and then a "net ads
