1.1.4 - TTLS - missing attributes
Hi list!
Recently upgraded from 1.1.3 to 1.1.4 to support EAP-PEAP for Windows
Vista clients. That works fine but now I got problems with missing reply
attributes for Mac OSX clients using EAP-TTLS.
FreeRADIUS sends an Access-Challenge with the correct attributes but
they are missing from the final Access-Accept.
If I use eapol_test client it works fine.
I used the freeradius.spec file for Suse to build the server. The file
is for 1.1.3. I simply changed the version number to 1.1.4.
Here is the debug output from OSX.
