I have created group called readonly1 in ldap server and added ldap user "jimmy" member of that group. When I try to access he is not getting ldap group access. Whereas I created  local group readonly1 and added jimmy" into that group it works fine.

dn: cn=readonly1,ou=Group,dc=ndmacb,dc=local
objectClass: posixGroup
objectClass: top
cn: readonly1
gidNumber: 550
memberUid: jimmy

Am I missing any config in ldap side? Thanks for your help!
