[Samba] Problems with smbpasswd: any local changes are discarted after connection request

Hi,

Can anybody confirm the following problem:

Sequence:

bash-2.05# grep ankerpos /usr/samba.moonrock/private/smbpasswd
ankerpos:921:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX:[U
         ]:LCT-0

bash-2.05# /usr/samba.moonrock/bin/smbpasswd -c /usr/samba.moonrock/lib/smb.conf
ankerpos
New SMB password:

Retype new SMB password:

bash-2.05# grep ankerpos /usr/samba.moonrock/private/smbpasswd
ankerpos:921:4CD849F7C109C5D7B85EBEA904A749B9:1CC6D72446271E9697044BC68DB72678:[U
         ]:LCT-0

bash-2.05# smbclient -L moonrock.admin -U ankerpos
Password:

session setup failed: NT_STATUS_LOGON_FAILURE
bash-2.05# grep ankerpos /usr/samba.moonrock/private/smbpasswd

[Samba] Problems with smbpasswd: any local changes are discarted after connection request

This issue was by design (see release notes of 3.0.2a), since the LCT
field is used to grant a user access. Point is LCT-X should != LCT-0.

Regards

Lieven
