an Entry has attribute uofsGroupRole that may contain values like :

only user with matching uid may see this attribute and its value.

I tried :
access to attrs=uofsGroupRole
   by dn.regex="uid=$1,ou=nsids,ou=people,dc=usask,dc=ca$" read

And it did not work as required. I know the problem in regex, but I can not
find it.

The final dollar sign in the 'by' clause needs to be escaped with a
second dollar sign - like this example from the slapd.access manpage:

            access to dn.regex="^(.+,)?uid=([^,]+),dc=[^,]+,dc=com$"
                by dn.regex="^uid=$2,dc=[^,]+,dc=com$$" write

In your case, you could probably simplify the 'by' clause like this:

access to attrs=uofsGroupRole
   by dn.exact,expand="uid=$1,ou=nsids,ou=people,dc=usask,dc=ca" read

Thank you. I will test it today and will be back with a result. It is a shame I had not noticed such a thing...

Make sure that you have a rule that will deny access to other users.
