New LDAP devices are not automatically being added into PAM. When manually refreshing the LDAP device group in the UI, the following error occurs for those devices.
PAM-LDAP-0016: Error adding device CN=Machine1,OU=..... PAM-CMN-0354: Device domain name is required.
Privileged Access Manager, all versions
The errors will occur when the DNS host name is not set for the device in Active Directory.
Update the devices in Active Directory and add a DNS host name, then refresh the LDAP device group again. This time the refresh will be successful.
