WSO2 EMM: Error in obtaining token with Password grant type

Question

EMM Build: 2.0.1 OS: RHEL 7.2 (x64)

Issue:

I am in the middle of the enrollment for an IOS device and during step 2, when it asks for domain/username and password, when I hit submit, I receive the following error:

HTTPS Status 500 - org.mozilla.javascript.EcmaError: Cannot read property "accessToken" from null (/emm-web-agent/modules/enrollments/ios/agent-controller.jag#53)

The stack trace is:

I have configured the tenant and provisioned the tenant's admin user. I am logging into EMM as the tenant's admin user and attempting to enroll the device as this user.

I've also tried skipping the domain during registration (leaving it blank as was suggested in this issue: WSO2 EMM server Cannot read property "accessToken" from null ) but it's not working.

I have attempted this both as a super domain admin as well as the tenant admin and both times, it's failed.

Any ideas what may be causing this? Please help...Thanks!

Answer 1

Please Use the tenant domain of users tenant for the domain field in the agent login screen if you are using a tenant user account for the enrollment.

Keeping the tenet domain filed empty is only acceptable if you are using a user account from the super tenant.
