WLS Will Not Connect to Active Directory on Port 636
(Doc ID 2195595.1)
Last updated on SEPTEMBER 03, 2020
Applies to:Oracle WebLogic Server - Version 126.96.36.199.0 and later
Information in this document applies to any platform.
On : 188.8.131.52.0 version, WLS Security
WLS server in production mode that will not connect to AD server on port 636. It will connect on 389 just fine, but not secure port on 636. There is a virtually identical Dev instance that will connect
The following works:
ldapsearch -x -LLL -H ldaps://host.domain.net -D REDACTED -w REDACTED -b"DC=domain,DC=net" -s sub "(objectClass=user)" sAMAccountName
This means the host can connect to the AD server just fine. WLS will not.
The error is this:
<Sep 22, 2016 4:42:11 PM CDT> <Warning> <Security> <BEA-099117> <The LDAP authentication provider named "ADLDAP" failed to make connection to ldap server at ldaps://example.com:636, the error cause is: Connection timed out.>"
-- Note "example.com" is the literal name in the log.
When changing the Host to "FAKE.domain.net" and restarted the admin console, the error message changed to:
<Sep 22, 2016 4:34:07 PM CDT> <Warning> <Security> <BEA-099117> <The LDAP authentication provider named "ADLDAP" failed to make connection to ldap server at ldaps://FAKE.domain.net:636, the error cause is: FAKE.domain.net: unknown error.>
The first thought of why this is failing is because of SSL improperly set up for port 636 as it was working on 389.
