When clicking the `Click to Enroll` button, Casa launches the `io.jans.agama.bioid.enroll` flow on the authorization server. This flow queries the BioID database for existing enrollments for the user. If the user has not enrolled, the flow presents the BWS GUI for enrollment. Upon success, the flow redirects back to a Casa landing page. Deletion of credentials is not supported as of now because Casa is unaware of enrollment status of a user. diff --git a/jans-casa/plugins/bioid/.metadata/.plugins/org.eclipse.m2e.logback.configuration/logback.1.16.3.20211002-1029.xml b/jans-casa/plugins/bioid/.metadata/.plugins/org.eclipse.m2e.logback.configuration/logback.1.16.3.20211002-1029.xml new file mode 100644 index 00000000000..4512556056c --- /dev/null +++ b/jans-casa/plugins/bioid/.metadata/.plugins/org.eclipse.m2e.logback.configuration/logback.1.16.3.20211002-1029.xml @@ -0,0 +1,41 @@ + + + + %date [%thread] %-5level %logger{35} - %msg%n + + + OFF + + + + + ${org.eclipse.m2e.log.dir}/0.log + + ${org.eclipse.m2e.log.dir}/%i.log + 1 + 10 + + + 100MB + + + %date [%thread] %-5level %logger{35} - %msg%n + + + + + + WARN + + + + + + + + + + + + + diff --git a/jans-casa/plugins/bioid/extras/agama/code/io.jans.agama.bioid.enroll.flow b/jans-casa/plugins/bioid/extras/agama/code/io.jans.agama.bioid.enroll.flow new file mode 100644 index 00000000000..c1f5b1522a7 --- /dev/null +++ b/jans-casa/plugins/bioid/extras/agama/code/io.jans.agama.bioid.enroll.flow @@ -0,0 +1,22 @@ +Flow io.jans.agama.bioid.enroll + Basepath "" + Configs conf + Inputs bioid_enrollment_code login_hint +bioid = Call io.jans.agama.bioid.BioIdService#new conf +idp = Call io.jans.agama.bioid.IdentityProcessor#new +bioid_verification = Call idp validateBioIdCode login_hint bioid_enrollment_code +When bioid_verification is false + error_map = {success:false, error: "Failed to verify BioID code"} + Finish error_map +enrolled = Call bioid isEnrolled login_hint +When enrolled is false + token = Call bioid getBWSToken login_hint "enroll" + enroll_map = {token:token, return_url:conf.host, state: "abcdef"} + enroll_result = RRF "bioid.ftlh" enroll_map true + When enroll_result.error is not null + error_map = {success:false, error: "Enrollment failed; please try again later."} + Finish error_map + success_map = {success:true, data: {userId: login_hint, status: "success"}} + Finish success_map +error_map = {success:true, data: {status: "enrolled", userId: login_hint}} +Finish error_map diff --git a/jans-casa/plugins/bioid/extras/agama/project.json b/jans-casa/plugins/bioid/extras/agama/project.json new file mode 100644 index 00000000000..c7a9cbe8423 --- /dev/null +++ b/jans-casa/plugins/bioid/extras/agama/project.json @@ -0,0 +1,18 @@ +{ + "projectName": "casa-bioid", + "author": "SafinWasi", + "type": "Community", + "version": "1.0.0", + "description": "A helper project for Jans Casa BioID plugin", + "noDirectLaunch": [], + "configs": { + "io.jans.agama.bioid.enroll": { + "host": "https:///jans-auth/fl/callback", + "endpoint": "https://bws.bioid.com/extension/", + "appIdentifier": "", + "appSecret": "", + "storage": "", + "partition": "" + } + } +} diff --git a/jans-casa/plugins/bioid/extras/agama/web/bioid.ftlh b/jans-casa/plugins/bioid/extras/agama/web/bioid.ftlh new file mode 100644 index 00000000000..eec97a20fe5 --- /dev/null +++ b/jans-casa/plugins/bioid/extras/agama/web/bioid.ftlh @@ -0,0 +1,968 @@ + + + + + + + BWS Unified User Interface + + + + +
