Re: [Fedora-directory-users] roles and access control

a question: we have a requirement where only users that have a role are able to see role membership. so if i have role A, i can see the membership for role A (search on nsRole=<roleA>) but cannot necessarily see role B members, etc. the same restriction applies when pulling the nsRole attribute.


is there any way (via aci) to support this? i've implemented a plugin (actually 2 - a computed attribute and preop) that supports this but wanted to make sure that i wasn't missing something in aci setup that would accomplish the same thing.

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.

Thanks, Gary
