Null Pointer Exception while configuring identity provider proxy using OpenAM

[jean.austin]

I am new to OpenAM and trying to learn by setting up an authentication solution involving a SAML2 service provider, SAML2 IdP Server, SAML2 IdP proxy.

I am able to set up a service provider, an identity provider and currently at the stage of setting up the IdP proxy “Step3: Configuring the Identity Provider Proxy (machineb)” in the guide SAMLv2 IDP Proxy Part 1. Setting up a simple Proxy scenario. I am able to complete till “Step 3: b” and when I try “Step 3: c”, I am getting the Null Pointer Exception.

My set-up is slightly different and I can map it like this:

• machinea.sp.com is http://sp1.sp.com:8080 : The machine that will function as a SAML2 Service Provider (SP)
• machineb.idpproxy.com is http://openam.idam.com:8080/OpenAM-11.0.0 : The machine that will work as the SAML2 IdP Proxy
• machinec.idp.com is http://idp1.idp.com:8080/OpenAM-11.0.0: The machine that will assume the role of a SAML2 IdP.

Each of these are set up as a Virtual box VMs on my Mac OS X.

My circle of trust is spcot instead of cot and realm is /sprealm.

The stack trace I get on the web page after submitting the changes is:

Thanks Peter.
Upgraded to OpenAM 11.0.2 and I did not come across this issue.
