URL encode / decode for uid #22
Description
Hi. We are trying to use the UserPrincipalName entry from MS AD as the UID field. In this case Synapse replaces the @ in the username with a slash (/) and performs the url_encode operation when accessing the API. Thus, the string /%40name%2Fdomain%3Adomain is formed in the URL.
However, matrix_corporal does not do this, and when we using name/domain format names, it substitutes them directly into the URL. As a result, for "id": "@name/domain:domain" record in policy.json the API is accessed at /_synapse/admin/v1
/users/@name/domain:domain/login which results in the error code=400 wrapped=M_UNRECOGNIZED: Unrecognized request
