HOW to make posixGroup a memberOf another posixGroup?? ...
You mean nested groups?
Deploying posixGroup is the very same concept like Unix groups in
/etc/group. And there is no such concept like nested groups there.
objectclass ( 184.108.40.206.220.127.116.11 NAME 'posixGroup'
DESC 'Abstraction of a group of accounts'
SUP top STRUCTURAL
MUST ( cn $ gidNumber )
MAY ( userPassword $ memberUid $ member $ description ) )
and where is "memberOf" ??
The attribute 'memberUid' contains the numeric Unix UID of all member
users of a 'posixGroup'. But where do you have this declaration with
attribute 'member' from? Normally it's not declared with attribute
memberOf is a completely different thing. It's a dynamically generated
back-link from the user's entry to all the group entries a user is a
member of. It cannot be used in conjunction with 'posixGroup' though.
