Environment

Release : 20.2

Component : DX NetOps Spectrum OneClick

Cause

The "User By Pattern" was configured in the OneClick LDAP configuration. The ldap-grps-mappings-config.xml configuration only supports "User by Search"

Resolution

Change the User Name lookup to "User by Search" in the OneClick LDAP configuration page and restart the tomcat service.
