[Samba] Storing Profile remote on Samba PDC only works for one user

Hello,

actually I am trying to implement a samba PDC server with a LDAP backend
where user are authenticated with. Additionally the users' profiles
should be stored on it, whicht only works for one user, not the 3
other. The point is, I don't see the difference between them so it
should work for all or none.

This is what I have in my smb.conf regarding this:

[global]

        logon script = logon.cmd
        logon path = \\%L\profiles\%U\%a
        logon drive = H:
        domain logons = Yes

[profiles]
# Provide a specific roving profile share
# the default is to use the user's home directory
# The permissions on the profiles directory should be
# chmod 1757 /exports/home/samba/profiles
# drwxr-xrwt    5 root     root         4096 May  1 08:43 profiles
[profiles]
   comment = Users profile
   path = /exports/home/samba/profiles
   valid users = "@Domain Admins" "@Domain Users"
"@Domain Guests" "@smbusers"
   read only = no
   create mask = 0660
   directory mask = 0770
   nt acl support = yes
   browseable = no
   guest ok = yes
   printable = no
   hide files = /desktop.ini/outlook*.lnk/*Briefcase*/
   guest ok = yes
   profile acls = yes
   locking = No

For one user, XXXXXXX_admin, this works fine. But the funny thing is,
its profile comes to /exports/home/samba/profiles/XXXXXXX_admin NOT
/exports/home/samba/profiles/XXXXXXX_admin/Win2K when accessed with
windows2000. Why is the %a ignored (debian samba package 3.5.5)? Despite
of that, it basically works.

This is an LDAP output for the working user:

ldapsearch -x -b "dc=XXXXXXXsystems,dc=de"
"(&(|(objectClass=sambaAccount)(objectClass=sambaSamAccount))(objectClass=posixAccount)(uid=XXXXXXX_admin))"

For all other users, when they log in the profile directory is
successfully created /exports/home/samba/profiles/XXXXXXX_user, but
there never one file is put to. Windows puts no errors out or claims
about not finding/accessing/exisiting profile. I can put files into the
samba share being the profile with no problem.

This is an LDAP output for such a user:

Well, what at any chance could yield to such an error, where should I
start to search further? ATM I have no clue what to debug next.

Kind regards, Konsti

[Samba] Storing Profile remote on Samba PDC only works for one user

Hello :-)

Meanwhile I found out why the %a in my "logon path" was not respected,
there was an entry in my LDAP user entries overriding this. I removed it
and now the %a ist respected,
/exports/home/samba/profiles/XXXXXXX_admin/Win2K is created _and_
populated only for XXXXXXX_admin, only created and _not_ populated for
the other users (works also from WinXP with %a becoming WinXP).

I have this issue on WinXP clients _and_ Win2k clients. 

I found out to enable userenv.log on the windows clients:

This is the user logging in:

I see the user is only reated as a guest and the admin as an
admin. Because both of them being treated as a guest I suppose both also
should be treated as a user and as this windows should do save the
remote profile (this is not done for guests only).

But my LDAP structure is intedend to handle both as users also. Where
can the error be? Can there be an error in Group Mapping or group
memberships or some sort of that? Both user are members of Domain Users
in my LDAP entries though...
