Changing LDAP for CROWD

I’m changing the connection type from LDAP Gitlab users to the Crowd. I am having positive difficulties for user users should be updated with the same accesses to the projects.
I set up a connection with the crowd and it’s perfect.
I have tried to change any “Provider” database from existing users from “ldapmain” to “crowd” but at log in asks to reset a password it displays User or password error.

version. 10.0.3
