[Pkg-samba-maint] Bug#505452: samba: Usernames lovercase not working

[Martin Sin]

Package: samba
Version: 2:3.2.4-1
Severity: normal

Hi,
I have problem with Windows 98 PC. Usernames are not lovercase every time.
Here part of of my log:

-----
init_sam_from_ldap: Entry found for user: ucitel
  check_ntlm_password:  authentication for user [UCITEL] -> [UCITEL] -> [ucitel] succeeded
-----

There it is ok, but another user:

-----
init_sam_from_ldap: Entry found for user: g532007
  check_ntlm_password:  Authentication for user [G532007] -> [G532007] FAILED with error NT_STATUS_WRONG_PASSWORD
-----

It is interesting, there is problem with usernames XSomeNumber (a642008,e472006 and so on).
If username looks like: ucitel, tobi, vokat, student, ... It is OK every time. 
LDAP usernames are in lovercase and login into Windows XP works ok.

In /etc/smb.conf I have:

.....
lanman auth = yes
.....

I have tried 
.....
username level = 10
.....

too, but it still not working.

Best regards for your help and sorry for my bad English,
Martin Sin.
