Description

The issue occurs when the following option is enabled: LDAP Tree Menu -> General -> LDAP User Auto Provisioning -> Auto provision users into LDAP from the following sources -> GUI (Manually created local users).
This behaviour is tracked as a known issue (ID 1205032) in v6.6.7.
As a workaround, disable Auto-provision users into LDAP from the following sources: GUI (Manually created local users) to resolve the error in v6.6.7.
However, the known issue has been fixed in FortiAuthenticator v6.6.8.
