RH-SSO user's group memberships are not updated after synchronization

Environment

• Red Hat Single Sign On (RH-SSO)

  • 7.1

• LDAPv3 Server (used as User Federation Storage provider)

• The following is the use case that causes the issue (tested with RH-SSO 7.1 and Red Hat Directory Server LDAP):

  • a Ldap Group "X" is directly updated in the LDAP server side in order to include a User "Y" as a member
  • after a SYNC in the RH-SSO Admin Console, the Ldap Group "X" is not displayed for User "Y" as being a member of it
  • the Ldap Group "X" is not visible in the "Groups" tab of the User "Y", but it's only visible in the "Members" tab of the group itself
