Secondary LDAP server not show in sign-in page

Summary

Secondary LDAP server not show in sign-in page, but LDAP search is working.

Steps to reproduce

  1. Add secondary LDAP server in gitlab.rb configuration
  2. Reconfigure Gitlab
  3. Go to sign-in page to see the result

What is the current bug behavior?

Only one (main) LDAP server shown in sign-in page. For example, if I have main server named "AD" and secondary named "LDAP", only "AD" is shown. If I switch their places in gitlab.rb, then only "LDAP" is shown. However, sudo gitlab-rake gitlab:ldap:check shows output from main and secondary servers.

What is the expected correct behavior?

Login forms for all LDAP servers should be shown in sign-in page.
