MSCHAPv2 with EAP-TTLS or PEAP will NOT work with LDAP. as explained
almost everywhere, and especially here :

You need a cleartext password or a NT_Hash to authenticate with MSCHAPv2.

Only EAP-GTC will work with LDAP if I'm not mistaken.

And by the way, your debug output show a request using PAP. PAP and EAP
are two completly different things, which different requirements.

This won't change that you can't authenticate with EAP-TTLS/PEAP and
MSCHAPv2 against a LDAP directory. (Well, except if you're using Novell
eDirectory with the Central Password management, but that's another story).
