I had to comment out the declaration of passwd (compilation error since 
it is defined in the function) and the patch worked and the output 
below, can you tell me what it means ?
My guess is next if fails (since the next debug is not printed)
if (snmp_oid_compare(Auths[i]->sa_oid, Auths[i]->sa_oid_len,
                             name, namelen) == 0)


smux: [smux_auth_peer] Authorizing: SNMPv2-SMI::enterprises.3317.1.3.1, 
password
smux: [smux_auth_peer] Checking OID: SNMPv2-SMI::enterprises.674.10892.1 (0)
smux: [smux_auth_peer] Checking OID: SNMPv2-SMI::enterprises.3317.1.3 (1)
refused smux peer: oid SNMPv2-SMI::enterprises.3317.1.3.1, descr radiusd
