Dears,

Assume there are several entries uner the "people" directory. 
    uid=User1,ou=people,dc=migu,dc=com
    uid=User2,ou=people,dc=migu,dc=com
    uid=User3,ou=people,dc=migu,dc=com
    uid=User4,ou=people,dc=migu,dc=com

A posix group contains User1 and User2:
dn: cn=admin,ou=group,dc=migu,dc=com
objectClass: posixGroup
memberUid: User1
memberUid: User2

I need a permission to allow the members of "admin" (here User1 & User2) login while others can not. What's the access list would be like?

I tried following, but not work.
access to dn="[uid=] + ([cn=admin,ou=group,dc=migu,dc=com])/memberUid + [,ou=people,dc=migu,dc=com]"
by anonymous auth

also tries following, not work either.
access to dn="cn=admin,ou=group,dc=migu,dc=com" attrs=member,enrty
by anonymous auth

Appreciated for any help.
