Description of problem: When both ldap and htpasswd IDPs are configured, and if LDAP query took more time than allowed Request timeout(default is 60s), user fails to login when credentials from htpasswd are used. Even though request timeout exceeds, it seems logical to try the other IDP. login succeeds if the order of htpasswd and ldap IDPs are reversed. Version-Release number of selected component (if applicable): 4.3 How reproducible: Always Steps to Reproduce: 1. Apply ldap IDP followed by htpasswd IDP 2. break the connection between ldap server and oauth-server. I achieved this by changing ldap server port number 3. trying to login as user configured in in htpasswd using `oc login` Actual results: login fails with "Error from server (InternalError): Internal error occurred: unexpected response: 504" Expected results: login to succeed Additional info:
I think this must have been there at least since 4.1. A solution to consider is to set the timeout the ldap library uses for connections (not the timelimit for searches, that's different) to half/portion of our request timeout.
