[Samba] is this bug or what - samba 3.0.2

[boka]

Hi !

I had working conf of samba 3.0.0 with ldap backend. After upgrade to 
3.0.2 i have found problem with /var/lib/samba folder - wins not 
working, groupmapping etc.

Permissions to this folder and files inside should be 0755, but on my 
PDC machine this folder and files have 0644 rights. When i manually 
change permissions it start working.

Do You have any patch for this ?
