Descriptions

GitLab 9.4.x before 9.4.2 does not support LDAP SSL certificate verification, but a verify_certificates LDAP option was mentioned in the 9.4 release announcement. This issue occurred because code was not merged. This is related to use of the omniauth-ldap library and the gitlab_omniauth-ldap gem.

GitLab en versiones 9.4.x anteriores a la 9.4.2 no es compatible con la verificación de certificados SSL LDAP, pero se mencionó la opción LDAP verify_certificates en el anuncio del lanzamiento de la versión 9.4. Este problema ocurrió porque el código no se combinó. Esto está relacionado con el uso de la biblioteca omniauth-ldap y la gema gitlab_omniauth-ldap.
