[keycloak-user] LDAP user group membership not syncing

Hi everyone I'm trying to sync the LDAP groups into Keycloak but it doesn't update the membership if I add or remove it from a group in LDAP. I was able to sync the groups and its users into Keycloak correctly if those wasn't provisioned before. For example, if the user already exists in Keycloak DB (provisioned from LDAP) and I remove it from a LDAP group (also provisioned from LDAP), the user in Keycloak continues to being a member of the group in the Groups tab of user's details screen and in client's group mappers. However, if I open the Members tab of group's details screen the user was removed from the group. Is there any way to solve this problem? Because of my company policy I can't use Keycloak to manage the groups. I'm using Keycloak 2.5.1. Thanks for the help -- Luiz Carlos
