samba - Apr 2003 - migration of samba 3.22a to Samba 3.23a - 2 possible bugs

How do you do !!!
  Pereshel with samba 3.22a on samba 3.23a (for support LDAP mapping group), 
did not change the config file - has installed in the same directory, has 
noticed 2 possible bugs:
1. after performing
    root# pdbedit -i tdbsam -e ldapsam -g
 the groups were orderly exported in LDAP directory, but with full absence 
privelege:

[root@bene bin]# ./smbgroupedit -l
ldapsam_open_connection: connection opened
ldap_connect_system: succesful connection to the LDAP server
ldapsam_setsampwent: 12 entries in the base!
Entry found for group: 1002
Attribute description not found

As be ? Privelege do not allow to use these groups for conferring user 
authority manager and etc.

2. On samba 3.22a user could remove attribut Read with file or files, now file 
ALWAYS ReadOnly i.e. attribut Read to remove not possible - that to do ?
