[keycloak-user] Users (related to LDAP) are gone when I change the username

[Marek Posolda]

Yes, I was wondering that maybe you will see some error like this. And 
+1 to set some other non-changeable attribute as "uid" . I am sure that 
it's doable with custom LDAP mapper, which will add the value just 
during the registration time, but not update it later. Maybe the best is 
to use just the first part of the "initial" email as username. Something 
like:

- User registers with john123 at email.com
- Mapper will extract, just the first part of the email, so "john123" 
and use it as RDN of LDAP. So user in LDAP will be saved like 
"uid=john123,cn=users,dc=example,dc=com"
- When email is changed to "john123-updated at email.cz", the UID will 
remain unchanged and will be still "uid=john123,cn=users,dc=example,dc=com"

Maybe timestamp is useful as well, not sure.
