[Samba] 2.2.5 talking to 3.0.2: can join, but not use a Domain

[Stefan Froehlich]

Hello,

I have a Samba client (jessica, running on 2.2.5), which has joined a
Domain with a Samba PDC (bertha, running on 3.0.2). I have done:

| jessica:/var/log/samba#  smbpasswd -U root -j MEITNER 
| Password: 
| Joined domain MEITNER.

And jessica is as well in the LDAP-database, maintained by the PDC. But
now, I want to log in and miserabely fail:

| sfroehli at tanja:~$ smbclient //jessica/www -U sfroehli
| Password: 
| Domain=[MEITNER] OS=[Unix] Server=[Samba 2.2.5]
| tree connect failed: NT_STATUS_WRONG_PASSWORD

A long while of digging in the log files revealed the following. On
jessica:

| [2004/02/15 22:28:43, 4] rpc_client/cli_netlogon.c:cli_net_req_chal(221)
|  cli_net_req_chal: LSA Request Challenge from BERTHA to JESSICA: 7CDE1E0D8E84D0C5
| [2004/02/15 22:28:43, 4] rpc_client/cli_netlogon.c:cli_net_auth2(132)
|   cli_net_auth2: srv:\\BERTHA acct:JESSICA$ sc:2 mc: JESSICA chal D1872E31A6704034 neg: 1ff

And on bertha:

| [2004/02/15 22:28:43, 5] libsmb/credentials.c:cred_session_key(61)
|         clnt_chal: 7CDE1E0D8E84D0C5
| [2004/02/15 22:28:43, 5] libsmb/credentials.c:cred_assert(123)
|         challenge : D1872E31A6704034
| [2004/02/15 22:28:43, 5] libsmb/credentials.c:cred_assert(124)
|         calculated: A23147887D28D908

So the authentification goes completely wrong. How can this be? After a
good while of searching, I found some suspicious entries in the
logfiles, whenever jessica (re)joins the domain:

| [2004/02/15 23:04:06, 5] rpc_server/srv_samr_nt.c:set_user_info_pw(2878)
|   Attempting administrator password change for user jessica$

|   convert_string_internal: Conversion error: Illegal multibyte sequence(HI)

Is this critical? If yes, how to circumvent it? I have

| display charset = ISO8859-15
| unix charset = ISO8859-15
| dos charset = CP850

which seems to work for the filesystems, but perhaps there is some other
internal problem with odd characters?

Please help!

Regards,

Stefan
