I wanted to load the template at display time rather than load time, so that it's easy to update on the fly. Honestly, I think we should do this with all our templates: the risk of ending up with malformed templates is far outweighed by the improved turnaround time for an admin trying to update them. --- changelog.d/9275.feature | 1 + docs/sample_config.yaml | 32 +++++- synapse/config/_base.py | 39 +------ synapse/config/oidc_config.py | 3 +- synapse/config/sso.py | 33 +++++- synapse/handlers/sso.py | 2 +- .../res/templates/sso_auth_account_details.html | 115 +++++++++++++++++++++ synapse/res/templates/sso_auth_account_details.js | 76 ++++++++++++++ synapse/res/username_picker/index.html | 19 ---- synapse/res/username_picker/script.js | 95 ----------------- synapse/res/username_picker/style.css | 27 ----- synapse/rest/consent/consent_resource.py | 1 + synapse/rest/synapse/client/pick_username.py | 79 ++++++++++---- synapse/util/templates.py | 106 +++++++++++++++++++ tests/rest/client/v1/test_login.py | 5 +- 15 files changed, 429 insertions(+), 204 deletions(-) create mode 100644 changelog.d/9275.feature create mode 100644 synapse/res/templates/sso_auth_account_details.html create mode 100644 synapse/res/templates/sso_auth_account_details.js delete mode 100644 synapse/res/username_picker/index.html delete mode 100644 synapse/res/username_picker/script.js delete mode 100644 synapse/res/username_picker/style.css create mode 100644 synapse/util/templates.py (limited to 'synapse/handlers/sso.py') diff --git a/changelog.d/9275.feature b/changelog.d/9275.feature new file mode 100644 index 0000000000..c21b197ca1 --- /dev/null +++ b/changelog.d/9275.feature @@ -0,0 +1 @@ +Improve the user experience of setting up an account via single-sign on. diff --git a/docs/sample_config.yaml b/docs/sample_config.yaml index 05506a7787..a6fbcc6080 100644 --- a/docs/sample_config.yaml +++ b/docs/sample_config.yaml @@ -1801,7 +1801,8 @@ saml2_config: # # localpart_template: Jinja2 template for the localpart of the MXID. # If this is not set, the user will be prompted to choose their -# own username. +# own username (see 'sso_auth_account_details.html' in the 'sso' +# section of this file). # # display_name_template: Jinja2 template for the display name to set # on first login.
