@Tom Browder: it seems to be a Symfony and SSO issue. Our developers team is facing issues when accessing simultaneously to different applications hosted on the server (in different tabs in the same browser). Symfony is basing SSO authentication on the domain name and URLs such as mydomain.fr/application1 and mydomain.fr/application2 are interpreted as being from the same domain (contrarily to URLs such as application1.mydomain.fr and application2.mydomain.fr). I do not know Symfony and I can't give you any more details on their problematic.
Hope it helps you to understand the need, Thomas -- Thomas WILLIAMSON • Technicien Systèmes et réseaux *Tél.* 05 49 61 25 25 (*interne *: 2235) *Eaux de Vienne - Siveer* • 55 rue de Bonneuil-Matours • 86000 Poitiers Le mer. 8 juin 2022 à 18:18, Tom Browder <tom.brow...@gmail.com> a écrit : > On Wed, Jun 8, 2022 at 07:12 Thomas WILLIAMSON < > t-william...@eauxdevienne.fr> wrote: > >> Hello, >> >> I have to take over an internal Web server that has been configured by a >> colleague who is no longer there.
