[keycloak-user] Keycloak 2.5.5 Ldap user group member ship is not syncing

Hi, I am using Keycloak 2.5.5 and I have created group-ldap-mapper. When I press “Sync LDAP Groups to Keycloak”, only groups are syncing to keycloak but not the users. I can sync users by pressing “Synchronize all users”. But I am missing ldap group membership info. Can someone help me to solve this issue. --Srini
