[keycloak-user] 2.4.0 Unable to register new user when LDAP is enabled

[Michael Anthon]

We have recently upgraded to 2.4.0 and are currently unable to create new users while LDAP is enabled.  Stack trace below.

The LDAP provider is configured with "Sync Registrations" turned off but this option seems to be ignored?

Any advice on this would be appreciated.

Thanks,
Michael
