Shared Secret auth doesn't register the login type correctly

[yspreen]

I have

matrix_synapse_ext_password_provider_shared_secret_auth_enabled: true
matrix_synapse_ext_password_provider_shared_secret_auth_shared_secret: 'xxx'

and yet, when I use the example script from their repo:

{'errcode': 'M_UNKNOWN', 'error': 'Unknown login type com.devture.shared_secret_auth'}

if I GET the login endpoint, there is

{
  "flows": [
    {
      "type": "m.login.password"
    },
    {
      "type": "m.login.application_service"
    }
  ]
}

After some digging, I found this commit that seems to disable it.

I think it should me mentioned in the doc.

am I breaking my element installation with this?

after setting matrix_synapse_ext_password_provider_shared_secret_auth_com_devture_shared_secret_auth_support_enabled, everything is now working. including element login. hard to say what caused the mentioned commit to disable it, and if that bug is still here

matrix-synapse-shared-secret-auth supports 2 different login types:

• com.devture.shared_secret_auth
• m.login.password

More details here: https://github.com/devture/matrix-synapse-shared-secret-auth#configuring

The playbook intentionally disables com.devture.shared_secret_auth because of https://github.com/vector-im/element-web/issues/19605

You can use m.login.password, however. See the m.login.password example here: https://github.com/devture/matrix-synapse-shared-secret-auth#usage

Alternatively, enable com.devture.shared_secret_auth using matrix_synapse_ext_password_provider_shared_secret_auth_com_devture_shared_secret_auth_support_enabled.
