Perhaps by using a targetfilter? e.g. assuming the role definition
entry is cn=MyRole,ou=people,dc=example,dc=com
dn: ou=people,dc=example,dc=com
...
aci: (targetattr="uid ||
cn")(targetfilter="(nsRole=cn=MyRole,ou=people,dc=example,dc=com)")(version
3.0; acl "Allow people to see other role members"; allow (read, search,
compare) roledn = "ldap:///cn=MyRole,ou=people,dc=example,dc=com";)
This allows people who are a member of MyRole to see the attributes uid
and cn in any entry under ou=people which matches nsRole=cn=myRole,....
(i.e. any entry which belongs to that role).
I haven't tried it out but this or something like this should work.
