Hello everyone,

I'm trying to see if/how the following access controls could be written:

1.  Allow * to read attributes (name, email, phonenumber) in entries in
the "cn=people,dc=uta,dc=edu" subtree *IF* attribute
(I can understand how to do this for the most part except for the *IF*

Here's a rule I wrote yesterday:

access to dn.subtree="ou=Users,dc=wfu,dc=edu"
         by * read

slapd.access(5) doesn't make clear that you can have all three qualifiers
on one access line, but you can.

2. Allows write access to users who have the attribute userPrivs=admin.

You may want to create an Admin group... at which point you can say:

access to dn.subtree="whatever"
         by group="cn=Admin,dc=group,dc=wfu,dc=edu" write
	by * break

For others: does the "group" specification used here respect "memberOf"?

In 2.2, another possibility would to be create a dynamic group who's members are determined by userPrivs=admin, and just give that group write access.
