the ACLs are indeed one of the importent topics. Therefore I was hoping,
that samba searches sub-trees for the login and auth information.
Than I could set up LDAP ACLs so samba looks up all information in the
tree for all groups (we do have only one fileserver for all user groups
togehter) and other ACLs "handel" the access for phonebook lookups from
That is what I was thinking off.
But if samba only browses one tree level and not the sub levels, than I
do have to think in an other direction.
Or what do you think?
Thanks and best regards,
