samba - Apr 2005 - Strange Problem with samBa client to access Windows shared Files ...

Hello everyone,
 
I'm having such a strange problem and i hope you'll understand the
situation.
I want to access files that are shared by a Windows server, from a linux box, by
using a login/pwd.
 
To be sure that these login/pwd has the good rights, i tested
it.
>From a windows box (which is in the same active Directory domain of the file
server -which is "AD") i tried to mount the remote HD whith the
login/pwd, and everything is ok.
it works fine
 
But when i use the mount command (from my linux Fedora box #mount -t smbfs ...)
i get somme errors but in my /mnt/partage, i can see directories. I also can get
trought these, but i cannot see any file .... quite strange isn't it. look :
 
[root@pcp423960pcs html]# mount -t smbfs -o username="AD\user"
//10.169.244.244/shares  /mnt/partage
27930: session request to 10.169.8.243 failed (Called name not present)
27930: session request to 10 failed (Called name not present)
Password:
[root@pcp423960pcs html]# ls /mnt/partage/
01/      5H/      5Q/      6S/      9R/      D0/      J1/      Login/
02/      5M/      6H/      6X/      AA/      H3/      J2/      V0/
4D/      5P/      6M/      8A/      ADMINNT/ H5/      J4/
[root@pcp423960pcs html]# ls /mnt/partage/6H/ACG/Directions/
[root@pcp423960pcs html]#

before the command, /mnt/partage is empty
 
I'm not at all an expert of Actif Directory but maybe it is impossible to
see the files of a filer if the source machine doesn't belong to the same
ActiveDirectory Domain.
 
And the docs i found about kerberos or samba are about the users of a Samba
SERVER, not about the client.
 
Maybe can someone help me, i sincerly hope because i already spent 3 days about
this problems.
Moreover, i do not want to return to the old web/Php config (which was an NT4
+esayPhp :-/ ... but it worked ...)
 
thanks
