Hai Steve,
Thanks for the reply. Right on the spot.
I checked my rights, and something was messed up there..
i did set some rights again but still same error. ( but read on, not entirly the same )
getfacl afdelingen/
# file: afdelingen/
# owner: root
# group: root
# flags: -s-
user::rwx
user:root:rwx
group::---
group:root:---
group:domain\040users:r-x
mask::rwx
other::---
default:user::rwx
default:user:root:rwx
default:group::r-x
default:group:root:r-x
default:mask::rwx
default:other::---
totaly correct..
root is mapped to "DOMAIN\Administrator" ( only the member server )
( the DC is DC and only DC with sysvol and netlogon share )
>Administrator works because you're mapping him to someone who has
>privileges. Admin doesn't enjoy any mapping.
but i did set the "Domain Admins" privileges, shouldnt that work also then?
and i didnt set any other privileges on the servers, only for "Domain Admins"
Ok, now the "strange" thing.
I did set the rights again, ( as example from the wiki )
Now the following happens.
1) DOMAIN\Administrator works fine everywhere.
2) DOMAIN\someuser works fine now on my member server, can access the shares, but SSO for webmail fails, popups domain auth..
3) Domain\Admin works fine for the webmail SSO, but not for the shares on the member server, popups domain auth. on the DC it works.
Arg... :-//
Someuser is member of "Domain Users"
Admin is member of "Domain users" AND "Domain Admins" ( setup the same as the original Domain\Administrator )
1 step forward and 1 back :-/
the member server is not in production so if you advice is format, consider it done..
the mail server is no option for reinstall..
* the mail server, i'll look into on a later moment, this is for the member server.
I need that one for my auto software installations through GPO setup.
any other suggestions?
Greetz,
Louis
