[Idpy-discuss] missing files in the master branch

Hi all, I am about to build the SATOSA directly from the official Github repository: https://github.com/IdentityPython/SATOSA though, I found some files are missing: the whole "docker/" directory which contains setup.py and start.py. I reviewed earlier releases and found that this directory and its content are there up to version with tag "v8.1.1" ( https://github.com/IdentityPython/SATOSA/tree/v8.1.1) and disappeared after that. 1. Can I rely on the latest version of the directory "docker/" and build it with the branch "master"? 2. Has the structure changed? I mean if I added them, would they work as expected? 3. Even though I have tried it (I believe it was version with tag "v6.1.0"). It was working, but at some point it does not release the SAML Response back from the SATOSA IdP to the SP (Shibboleth-SP). instead I got an error message like this: The error occurs at the first time (after clearing the caches, or just opening the browser), but later, if I re-opened the browser, it works normally. and that makes me think if it has something to do with that "docker/" directory being outdated. I reviewed the codes in "setup.sh", "start.sh" and could not tell if there is incompatibility with branch "master". I am looking for your guidance. Thank you. Best regards, Abubakur Sait
