particular problems.

looks ok, but I'm not absolutely sure about the quotation marks for
the username, they are not needed in any case.

testuser User-Password :="testuser"
I will try with only above entry in users file

OK, I found some positings about username_identity_check disabling for user
"anonymous"...here it is

I guess since somebody implemented this check, there must be some broken
NASes out there... and
the attached patch fixes this situation. If user sets
"username_identity_check = no" in
eap section it will disable this check. The default for this setting is

So, now I have added this patch to files eap.c, rlm_eap.h, and rlm_eap.c,
compiled. I will test it this on monday.I am expecting this patch will lead
to pass this anonymous user check phase in radius server.I will post you the
result on that. Please let me know if you are aware of this.

Not sure where we configure this phase2="autheap=MSCHAPV2" ? Are we at phase
2 yet ? I thought we have not passed the phase 1..can you pls clarify ?

I will test with the above patch - and see if we can pass the anonymous
identity check problem. If persists - I will recompile with original files
mentioned above, and test again to give you the full debug logs.
