Jiatao Tao edited comment on KYLIN-3562 at 10/29/18 7:33 AM: ------------------------------------------------------------- We cannot remove the logic that updates user when user login in directly cuz it sticks with LDAP. In this commit: https://github.com/apache/kylin/commit/3bcbaa88b97cf868ddf8f51a54b015ef3b7cc068, I refine the logic that updates the user, so in most case, it won't update the user. The next step may separate LDAP so the design can be cleaner. was (Author: aron.tao): We can not remove the logic that updates user when user login in directly cuz it sticks with LDAP.
