I tried to configure LDAP integration, but when I try to add users I get this error:

Unable to authenticate: error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed (unable to get local issuer certificate)

How can I fix this?

Hi @vmesquita

That generally means that the remote server doesn't have the issuer CA certificates installed so it's unable to verify it. You would need to import the CA certificate from the issuing CA (who singed your LDAP/AD server cert) into the XI server for it to validate properly.
