I'm trying to configure Pega 7.3.0 to authenticate SSO using SPNEGO, but i don't find any documentation step by step of this configuration, i tried the link:

https://docs.pega.com/how-implement-single-sign-using-spnego-and-jaas

But it's not so clear of how to configure, someone can help me with this?

My implementation is using Websphere 8.5 as Web Server on Linux (RedHat) and trying to connect on MS Active Directory (2012 R2) as LDAP.

Thanks!
