missing AVP 29 VSA 23 in the Radius Access-Request sent by ASA 5545-X 8.6

[guillerm]

Hello,

we are migrating from ASA 5520 Version 8.4(3) to ASA 5545-X Version 8.6(1)2 with the same configuration ;

we are stuck with a Radius authentication problem related to an ASA clientless ASA access ;

when we compare the Radius dialog between each ASA (the old one and the new one) and the same Radius ACS 5.3 server, we can see that the only difference is there is a missing AVP 29 VSA 23 in the Radius Access-Request sent by the new ASA-5545-X compared to the good one sent   by the old ASA 5520;

this AVP 29 VSA 23 carries the tunnel-group name as defined in the ASA configurtion ;

5545-X ad 5520 configuration files have been double-checked and compared : no difference between both files

any help would be appreciated to diagnose this problem

thanks in advance

This problem was solved by upgrading the 5545-X from version 8.6(1)2 to version 9.1.2;

nothing else changed
