Re: URGENT: Samba Won't Substitute %u In "Logon *" When LDAP Is Used

Version: 3.0.14a  (debian stable: 3sarge1)

I just upgraded to 3.0.22 (debian "testing") and have the same problem. I could really use some help on this one!!!

(I'm not currently subscribed to this list, so please CC me on any replies -- Thanks!)

I'm just about finished converting our company's network from NIS to
LDAP.  Part of that involved updating Samba to use that same directory
so all the information is maintained in one place.

Most everything is good, except that my roaming profiles won't work.  My
smb.conf file is attached.

Upping the log level eventually showed messages like this:

[2006/05/22 15:16:29, 5] smbd/filename.c:unix_convert(108)
   unix_convert called on file "%u"
[2006/05/22 15:16:29, 10] smbd/statcache.c:stat_cache_lookup(210)
   stat_cache_lookup: lookup failed for name [%U]
[2006/05/22 15:16:29, 5] smbd/filename.c:unix_convert(175)
   unix_convert begin: name = %u, dirpath = , start = %u

I traced this to the "logon path" configuration item.  Samba is choosing
the value from the smb.conf file because I don't have these values set
within the LDAP directory; I just want to use the default generated one.

However, it semes that Samba is NOT substituting the "%u" in this case
even though it was when LDAP was not in use.  At least "logon path" and
"logon home" are affected; maybe more.

To verify, I manually changed every "%u" in the smb.conf file to
"bcwhite" and then I can log on with my profile and home directory just
fine.  An okay solution for me, but the rest of my users might complain.

Since my users are expecting to return tomorrow (after a long weekend)
and use their WinXP machines, I'd appreciate it if someone can shed some
light on this problem asap.

Thanks much!!!
