Hybrid groups

Any of the structural group object classes can be extended such that group membership is described by a combination of static, dynamic, and nested member types. For example:

dn: cn=Group 10, cn=Groups, o=IBM, c=US
 objectclass: groupOfURLs
 objectclass: ibm-nestedGroup
 objectclass: ibm-staticGroup
 objectclass: top
 cn: Group 10
 description: Group composed of static, dynamic, and nested members.
 memberURL: ldap:///cn=Austin, cn=Employees, o=IBM, c=US??one?objectClass=person
 ibm-memberGroup: cn=Group 9, cn=Nested Dynamic, cn=Groups, o=IBM, c=US
 member: cn=Person 10.1, cn=Dept 2, cn=Employees, o=IBM, c=US
 member: cn=Person 10.2, cn=Dept 2, cn=Employees, o=IBM, c=US
