This article describes a scenario when you have Synchronized an LDAP group using Schemus tool, later on the group is shown as grayed out in the ClientNet portal with no possibility for a manual removal.
Example :
Email Security.cloud
When a user group is synchronized using an LDAP Sync method via Schemus synchronization tool, by design we do not offer a manual removal from the ClientNet portal but from the Schemus tool.
1 - In Schemus select the 'Groups' tab then click 'Modify'
2 - From the left pane select 'Filters'
3 - Enter name of the group as displayed in Schemus (usually 'domain\name') in the pattern column
4 - leave the Replacement field blank
5 - select 'Literal text' from the drop-down
Example :
Note : Save the configuration after you have completed the changes to your group in the filters tab, or proceed by clicking Next in order to check and verify the overall settings.
