Describe the bug
Getting "server error while authenticating" and "Error creating connection for startTLS: LDAP Result Code 200 "Network Error": dial tcp 2XXXX:30078: i/o timeout"

when trying to configure OpenLdap as a Auth provider. I have tried using LDAP admin user and even user under different organization unit. But getting the same error. Also not getting error under k3s logs or events.

To Reproduce

• Login in Rancher > User & Authentication >Auth Provide > Open Ldap
• Open Ldap configuration

With LDAP admin user

Result
Error creating connection: LDAP Result Code 200 "Network Error": dial tcp 2XXXXXXX:30078: i/o timeout
Expected Result

LDAP authentication is enabled
