Login Failure: Pool is empty and connection creation failed

Question

when I tried to SSO using Shibboleth IDP, a login Error occured, when username and password was submitted as, Login Failure: Pool is empty and connection creation failed.

My error logs are as follows

org.ldaptive.pool.PoolExhaustedException: Pool is empty and connection creation failed

Can anyone suggest me a way to solve this?

Old question, answer for google.

Check /opt/shibboleth-idp/conf/ldap.properties if your domain/IP and port are correct.

In my case i missed out that the image bitnami/openldap uses port 1389 by default.
