Thanks. It works.
I would suggest to have the "typo" on Gluu official docs modified:
section: Create AWS Custom Attributes in LDAP#
1) modify "objectclass" to "objeCtclasses:"
2) add colon after "attributeTypes"
Moreover, I have one question to ask.
I have an Android APP which calls AWS API Gateway.
I would like to add the authentication feature. When users login on Android APP, I would like to have AWS cognito (identity pool) to authenticate using Gluu server as user pool (federation SAML).
Do you have any instructions to follow? I am referring to this now: https://gluu.org/docs/ce/integration/saas/aws/
At the last step "SSO Testing#". it didn't behave as the video. I got the request redirected and it complained
"Web login service – Unsupported Request
The application you have accessed is not registered for use with this service.
I am looking forward to hearing your suggestions.
