Hello, I am using the freeradius-server version V3.0.x and have the problem that the data specified in the users file for the Ascend-Data-Filter attribute (from the Ascend vendor space) is not correct sent in the radius access-accept msg. Is this related to the rfc6929 extended-attribute 242 that I need to do something specific, the Ascend-Data-filter is sent as part of the vendor space Ascend(=529), so there is no conflict with the 242 extended-attribute of rfc6929? My users file contains the following: Ascend-Data-Filter = 0x01010100010203040a0b0c0d05200600000504d2020200000000000000000000, The radius output is : (12) Sent Access-Accept Id 222 from 138.203.10.191:1812 to 138.203.10.123:64397 length 0 .... (12) Alc-Default-Router = 10.50.2.1 (12) Ascend-Data-Filter = 0x (12) Class = 0x41444d494e31 (12) Finished request Waking up in 4.9 seconds. (12) <done>: Cleaning up request packet ID 222 with timestamp +184 Ready to process requests My wireshark shows for the ascend-data-filter the following " 1a 28 00 00 02 11 f2 22 20 27 7a 02 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00" In a previous version of freeradius V2.1.12. this is working fine, but I stepped up to version V3.0.8 to have support for the radius extensions RFC6929. Thanks, Regards, Katrien.
