-------------------------------------------------------------
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.
