Problem with smbpasswd in Version 3.0.8. Seems to encrypt password incorrectly. Login not possible. 
After setting the same password with smbpassword of 2.2.9 login is possible.

Samba 3.0.8 is configured with ldapsam_compat


Example:
  bash-2.03# ./smbpasswd smbtest10
  New SMB password:

  Retype new SMB password:

  bash-2.03# ./smbclient -s/usr/local/smb/system/config/<customersite>/smb.pdc2.conf -U 
  smbtest10 //pdc2-<customersite>/smbtest10
  Password: 

  session setup failed: NT_STATUS_LOGON_FAILURE

NOW CHANGING PASSWORD FROM A DIFFERENT SERVER UNDER 2.2.9 to same value

  bash-2.03# ./smbclient -s/usr/local/smb/system/config/<customersite>/smb.pdc2.conf -U 
  smbtest10 //pdc2-<customersite>/smbtest10
  Password: 

  Domain=[<domainname>] OS=[Unix] Server=[Samba 3.0.8]
  smb: \> quit

working Userentry-LDIF, changed with smbpasswd of 2.2.9
