[Samba] Samba3 shares cannot be mounted on linux box uisng cifs command , error "CIFS VFS: cifs_mount failed w/return code = -13"
well, I have configured the kdc client on the file server, joined the
domain using net ads join and it worked fine, again getnet group , getnet
passwd , wbinfo -u they all works perfectlly fine
I am also able to browse the shares from any windows machine joined to the
CCDC domain, but I am still not able to do ANY mount.cifs, not even form
linux boxes joined to the domain :-/
I have no idea what's happening.
P.S. another thing I have noticed is that from windows machines, when I try
to do a network map to a share on the samba4, it gives "Authentication
Failure", while it was working correctly before the migration.
I'm running short of ideas now, any help more than welcome!

If getent is working, then there should be no reason to leave & rejoin
the domain, but then again, there is no reason not to try it :-)

[Samba] Samba3 shares cannot be mounted on linux box uisng cifs command , error "CIFS VFS: cifs_mount failed w/return code = -13"
I have some more findings about this
it looks like getent does not get the right information from the Domain
Controller, in fact the domain user groups shows with NO member users:
getent group | grep "domain users"
domain users:x:10000:
root at seadog:~#
Now funny thing is that other folders for wwhich getent retrieves the users
correctlly are mounted fine . any idea why I don t see the users in getent?
for example:
root at seadog:~# getent group | grep "domain admins"
domain admins:x:10001:ieu94629,ieu94243,ftp3-admin,administrator
any idea?

Any error messages anywhere ?
Also when you say 'browse', can you give a bit more info, how are you
'browsing' and where are the shares, on the DC or somewhere else?

Well, that probably means what it says, for some reason, samba is not
recognising either your users or their passwords,
