Hi,
Relatively new to freeradius. Have had success testing an EAP-MD5
and EAP-TLS configuration. I have patched freeradius-server-2.1.10
to add EAP-AKA support but am experiencing a radiusd startup failure
as follows:
radiusd -X

Struggling with determining what is missing in my configuration that
might be causing this issue. I see that the above error
is coming from src/lib/valuepair.c but am having difficulty
determining the root cause. I've read doc and man pages
but so far cannot spot the problem.
I've placed the raddb directory under git version control to
easily track my changes. These are the changes I have made to
the freeradius delivered configuration:
