[Samba] because of ldap migration or bug 1345?

[Pablo Chamorro C.]

Since one week ago we managed to change the samba PDC authentication 
scheme to openldap, but we are having problems with the home directories 
from some XP clients.  After some time those homes are blocked and the 
users can not even list the contents (access denied).

Here some lines from the relevent samba log file:

[2006/02/03 12:46:19, 3] smbd/process.c:switch_message(685)
   switch message SMBntcreateX (pid 13680)
[2006/02/03 12:46:19, 4] smbd/uid.c:change_to_user(186)
   change_to_user: Skipping user change - already user

[2006/02/03 12:46:19, 3] smbd/open.c:open_directory(1356)
   open_directory: unable to stat name = .. Error was Conseguido
[2006/02/03 12:46:19, 5] smbd/files.c:file_free(385)
   freed files structure 10925 (0 used)

   error packet at smbd/trans2.c(2222) cmd=162 (SMBntcreateX) 
NT_STATUS_ACCESS_DENIED

is this happening because of the same bug 1345? 
(https://bugzilla.samba.org/show_bug.cgi?id=1345) or is it relate to ldap?

We have samba 3.0.5-2 under Red Hat 9.0.

Thanks,

Pablo Chamorro C.
