Failure to Connect to Active Directory Server (Manual)
Symptom
When manually specifying Active Directory servers SECURITY_AD_SERVER_AUTODETECT=false, the following message appears in the log file:
(Active Directory) Failed to connect to an available server, or no servers were available.
Cause
When specifying Active Directory servers manually, a mistake was made in the configuration parameters.
Resolution
- Ensure that the SECURITY_AD_SERVER_COUNT parameter is set to the number of Active Directory Servers available.
- Ensure that the 'n' suffix in the SECURITY_AD_SERVER_HOSTn and SECURITY_AD_SERVER_PORTn parameters are correctly specified. For example:
- SECURITY_AD_SERVER_COUNT=1 requires: SECURITY_AD_SERVER_HOST1, SECURITY_AD_SERVER_PORT1
- SECURITY_AD_SERVER_COUNT=2 requires: SECURITY_AD_SERVER_HOST1, SECURITY_AD_SERVER_PORT1, SECURITY_AD_SERVER_HOST2, SECURITY_AD_SERVER_PORT2
- SECURITY_AD_SERVER_COUNT=3 requires: SECURITY_AD_SERVER_HOST1, SECURITY_AD_SERVER_PORT1, SECURITY_AD_SERVER_HOST2, SECURITY_AD_SERVER_PORT2, SECURITY_AD_SERVER_HOST3, SECURITY_AD_SERVER_PORT3
- Ensure that the host(s) and port(s) are not misspelled.
- The port value is most commonly 389 or 636.
