Support customizable email branding during signup & password reset

[ghost]

Hello

I started the server with python -m sydent.sydent - everything seems to work but there is no info how I should configure web client or Android app to use the identity server.

Currently synapse gives this error:

2016-11-27 16:57:30,814 - synapse.http.server - 139 - ERROR - POST-53- Failed handle request synapse.http.server._async_render on <synapse.rest.ClientRestResource object at 0x7f5694cc1f90>: <SynapseRequest at 0x7f568ddf1518 method=POST uri=/_matrix/client/r0/account/3pid/email/requestToken clientproto=HTTP/1.1 site=8448>

Should I specify port (8090) too or will the server detect itself? If the port is specified in web client then it starts to spin but there is no response nor anything interesting in the logs. Really no idea what I'm missing here..

Thanks

The right place for sydent bugs is the sydent repo at matrix-org/sydent.

That said, running your own sydent is almost always the Wrong Answer, as you are then isolated from the rest of Matrix.

The actual solution to what you want here is probably matrix-org/synapse#1710, which would let your HS brand the emails correctly. Turning this bug into a tracker for supporting branded email validation.

Another solution would be to allow us to pass basic branding template info to the IS from the HS during the signup dance.

Closing as the synapse issue is now resolved (see matrix-org/synapse#1710 for more information)
