secd.ldap.noServers: LDAP Service Not Found Due to Missing SPN
Applies to
- ONTAP 9
- CIFS
Issue
Issue: experiencing LDAP server accessibility issues, specifically secd.ldap.noServers alerts for the vserver 'prod-fs' after decommissioning a Domain Controller.
When was the issue first observed?
- After Decommissioning one of our Active Directory Domain Controllers
Were there any recent changes or maintenance performed?
- We Pointed the NetApp to Different Domain Controllers, the LDAP health check shows it is communicating OK
Anything related in your environment? (features and applications in use, network configuration, etc.)
- There may be additional Firewalls in between but not enough information from the event log as to what port might be blocked
