LDAP + Active Directory Authentication Issue

[Luke Ramsden]

Thank you all. With your help I have made progress.

I can now successfully authenticate the user 'test' against Active
Directory if I open up another terminal and run:
radtest -t mschap test password localhost 0 testing 123

However, the 'no Auth-Type found' error still occurs if I send the request
from my console server. Is this because the request from the console server
needs to specify use of mschap?

Thanks again
