Login problem with REST API in Enterprise environment /Portal

NirmalOjha

Hello,

For some time now, I have been unable to login using REST API nor I am able to generate token. It used to be working but now it is not working. No configuration has been changed. I used the following URL pattern for generating the token but I get response as invalid username or password:

https://webadaptor.domain.com/arcgis/sharing/rest/generateToken 

Response:

{"error": {  "code": 400,  "message": "Unable to generate token.",  "details": [   "Invalid username or password.",   "Invalid username or password."  ] }}

The only user account that works with the above URL and REST API is the default admin account, any other account results in Invalid username or password.I can login to the portal fine with the browser https://webadaptor.domain.com/arcgis and it allows me to login using enterprise login.

Thanks.

Nirmal

I'm wondering if there is a service account in play somewhere that may be locked.  You said you're using SAML but then you also said the answer to question #4 originally was "shows Windows".  Typically, it would show Windows in the Portal Admin's security/config section if you were using IWA.  If your Portal is in fact configured to use Windows as its user and/or groups store, then you would likely be using a service account to authenticate with active directory in order to perform user and group lookups.  That account may be locked.  Other than that, I recommend checking with Esri support on anything further.
