Hi Andrew
I finally figured it out and here is what I did:
ACL
-----
access to attrs=uofsGroupRole val.regex="^([^:]+):.+$"
by dn.exact,expand="${v1}" read
by * none
Only attribute that contains users' dn within its value is available to
said user. It works exactly the way I want it. Only difference from
documentation is "${v1}" which explained here:
http://www.openldap.org/lists/openldap-bugs/200811/msg00078.html if you
are interested...
Thank you for your response,
Cheers

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
val.regex="uid=([^,]+),ou=nsids,ou=people,dc=usask,dc=ca.*$"
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
val.regex="uid=([^,]+),ou=nsids,ou=people,dc=usask,dc=ca.*$"
by dn.exact,expand="uid=$1,ou=nsids,ou=people,dc=usask,dc=ca" read
Make sure that you have a rule that will deny access to other users.
