I encountered an error while configuring Splunk to connect to LDAP.
Failed to retrieve a user with these settings. Consult your LDAP admin or see splunkd.log with ScopedLDAPConnection set to DEBUG for more information.
The LDAP settings you used probably are incorrect. Verify them with your LDAP admin.
Confirm the firewall(s) allow connections from Splunk search heads to the LDAP server.
