Since we have upgraded to ASYNCOS 8.0.1 external users who had read only access to Ironport are now not able to access.
System Admin > External authentication has been enabled with read only group name directory add to row.
AD (windows) the group name has been created and has assigned users.
but when I test LDAP server setting > External authentication queries > Test ---- I receive error "Matching LDAP record no groups found for identity <group name>"
Ive checked backed up config from before upgrade and the current config and I don't have any notable differences.
