While the CompTIA Security+ SY0-601 does cover the EAP framework, e.g., PEAP, EAP-FAST, EAP-TLS, EAP-TTLS, MS-CHAPV2, IEEE 802.1X, etc., this exam over covers such topics in a broad overview way IMO. I have looked on Udemy and other sites for a specific course that really drills down into the aforementioned topics in a far deeper way vs. the CompTIA Security+ exam does, but alas, I have not (yet) found any courses on this site, Udemy, Pluralsight, CBT Nuggets, etc. that really drills down into such topics in an in-depth sort of way, e.g., with a lot of labs to setup all of the aforementioned.
I would also like to see courses offered on setting up a Radius (or better, its replacement, "Diameter") server along with the various types of authentication and Lightweight Directory Access Protocol (LDAP), Federation, X.509, Security Assertion Markup Language (SAML), TACACS+, etc. (both setting it up with Windows Active Directory as well as Linux servers [no Windows server whatsoever], etc.).
Another area which I would love to see courses, virtual labs, etc. offered for is the various Signal Sign On (SSO) approaches, e.g., OAuth, OpenID, Kerberos, Shibboleth, etc. (again, not the broad overview / lightweight introduction that the Security+ exam provides, but an in-depth course / virtual lab(s) for such topics.
