Many directories set ACIs that allow users to add or remove themselves from groups such as mailing lists.
At Example.com, employees can add themselves to any group entry under the ou=Social Committee subtree, as shown in ACI “Group Members”.
In LDIF, to grant Example.com employees the right to add themselves to a group, you would write the following statement:
aci: (targettattr="member")(version 3.0; acl "Group Members"; allow (selfwrite) (userdn= "ldap:///uid=*,ou=People,dc=example,dc=com") ;)
This example assumes that the ACI is added to the ou=Social Committee, dc=example,dc=com entry.
