Freeradius 3.0.4 and 2+2 VSA issue

[Aleš Rygl]

Hi all, 

I have a problem using VSA encoded in 2+2 format, namely
those in dictionary.starent in 3.0.4 version of the Freeradius. The
server uses the dictionary supplied within the tarball. 

The server is
processing just accounting requests and saving the requests into a
detail file at the moment. But they are not decoded:

It seems
that just starent VSA are affected but I can see tha also
Attr-26.10415.23 is not decoded to 3GPP-MS-Time-Zone thought it is
present in /usr/share/freeradius/dictionary.3gpp 

The sample of
dictionary.starent: 

VENDOR Starent 8164 format=2,2

BEGIN-VENDOR
Starent

ATTRIBUTE SN-VPN-ID 1 integer
ATTRIBUTE SN-VPN-Name 2
string
ATTRIBUTE SN-Disconnect-Reason 3 integer
ATTRIBUTE
SN-PPP-Progress-Code 4 integer
ATTRIBUTE SN-Primary-DNS-Server 5
ipaddr
ATTRIBUTE SN-Secondary-DNS-Server 6 ipaddr
ATTRIBUTE
SN-Re-CHAP-Interval 7 integer
ATTRIBUTE SN-IP-Pool-Name 8 string


Though the attributes are not decoded you can still refere to then in
the configuration (i.e. no error is reported) so it looks like the
server knows them. 

radiusd -XC show no errors, the binary was built
from source and a .deb package was created. I can provide more samples
if needed. 

Thanks for help. 

Regards 

Ales
