I'm working on emulating a setup we already have in place for the purposes of testing different configurations.

The setup is as follows: we have a primary share server which stores users' home directories and the like. It is setup with Samba. This server authenticates against an active directory domain controller using LDAP.

I've been unable to get another box to emulate this setup. The new box will not even authenticate against the active directory server - there isn't a log of a success or failure on the AD server. However, Samba logs say that there was an error indicating no such user.

Here are my important configuration files, with some information removed for security purposes.

# entry should stop if the search in the previous entry turned
# up nothing. Note that if the search failed due to some other reason
# (like no NIS server responding) then the search continues with the
# next entry.
#
# Legal entries are:
#
#	nisplus or nis+		Use NIS+ (NIS version 3)
#	nis or yp		Use NIS (NIS version 2), also called YP
#	dns			Use DNS (Domain Name Service)
#	files			Use the local files
#	db			Use the local database (.db) files
#	compat			Use NIS on compat mode
#	hesiod			Use Hesiod for user lookups
#	[NOTFOUND=return]	Stop searching if not found so far

#

# To use db, put the "db" in front of "files" for entries you want to be
# looked up first in the databases
#
# Example:
#passwd:    db files nisplus nis
#shadow:    db files nisplus nis
#group:     db files nisplus nis

passwd:     files ldap
shadow:     files ldap
group:      files ldap

I can't think of anything else to supply you, but if there is anything please do let me know. I've been working on this for two full days now with no luck. I know pretty much everything is an older version, but realize that I am trying to emulate another machine so upgrading is not an option (these are all the versions our current, working box uses.)
