Documentation error
I use some LDAP server to authenticate my users. In the configuration section I try to get additional information about my users' groups but it wasn't working beacause of the french documentation.
In General Parameters > Authentication parameters > LDAP parameters > Groups > Searched attributes
Documentation is : English : Searched attributes: name(s) of the attribute storing the name of the group, spaces separated (default: cn). French : Attributs recherchés : nom(s) de l'attribut stocké dans le nom du groupe, séparés par des virgules (défaut: cn).
As "virgule" stands for "coma" and not "space", it couldn't work. Expected issue correction : fix french translation to indicate the suitable separator (e.g. "espaces" instead of "virgules").
