+                          Ascend Radius Options
+                                  or
+              What happens when a big vendor ignores an RFC
+
+
+  FreeRADIUS uses Vendor-Specific attributes to send the Ascend attributes.
+By default, Ascend NASes send the Ascend specific attributes as NON VSA's,
+which conflict with new RADIUS attributes assigned by the IETF.  This was
+a very bad screw-up by Ascend that still causes many headaches, but sometimes
+we have to live with it, so we try to cope the best we can.
+
+  If you see a large number of messages about invalid Message-Authenticator
+attribute, you most likely are affected by this problem, and should implement
+the first option.
+
+You have two options:
+
+o Enable VSA's on the Ascend/Lucent MAX:
+
+  This is by far the preferred method ( as it solves many other problems ).
+
+  Max6000/4000 Series TAOS with Menued Interface:
+
+    Go to Ethernet->Mod Config->Auth.
+    At the bottom of the menu, change Auth-Compat from "OLD" to "VSA".
+    Save your changes, no reboot is needed.
+
+    Go to Ethernet->Mod Config->Acct.
+    At the bottom of the menu, change Acct-Compat from "OLD" to "VSA".
+    Save your changes, no reboot is needed.
+
+  Max TNT/Apex 8000 Series TAOS with CLI:
+
+    nas> read external-auth
+    nas> set rad-auth-client auth-radius-compat = vendor-specific
+    nas> set rad-acct-client acct-radius-compat = vendor-specific
+    nas> write
+
+o Enable OLD attributes in FreeRADIUS
+
+  One note on this, Ciscos have an Ascend compatibility mode that
+  accepts only the OLD style Ascend attributes, just to make life more
+  interesting.  :)
+
+  You can make FreeRADIUS send the OLD style attributes by prefixing the
+  Ascend attributes with 'X-' in the 'users' file, sql table, ldap directory,
+  attr_filter module, etc...
+
+  Thus the VSA Ascend attribute:
+
+     Ascend-Data-Filter
+
+  becomes the OLD Ascend attribute:
+
+     X-Ascend-Data-Filter
