missing required dictionary attributes for standard pppd

[Igor A Tarasov]

Dictionary included with package radusclient-ng missing required attributes for pppd.
When pppd receive attribute, which is not defined in dictionary it DROP CONNECTION !!!

Steps to reproduce:
1) configure pppd for radius authentication
2) configure radius accounting with Acct-Interim-Interval at radius server

After first interval, pppd send AccountingRequest packet and drop connection with 'unknown attribute'

To fix this, need to include attributes, used by pppd to dictionary:

# RFC 2869
ATTRIBUTE Acct-Interim-Interval 85 integer

# Limit session traffic
ATTRIBUTE Session-Octets-Limit 227 integer

# What to assume as limit - 0 in+out, 1 in, 2 out, 3 max(in,out)
ATTRIBUTE Octets-Direction 228 integer

# Octets-Direction
VALUE Octets-Direction Sum 0
VALUE Octets-Direction Input 1
VALUE Octets-Direction Output 2
VALUE Octets-Direction MaxOveral 3
VALUE Octets-Direction MaxSession 4

Also, pppd unable to authenticate with radius, when Mictosoft MS-CHAPv2 authentication is configured because of no of this attributes defined in dictionary.

All this problems is very simple to fix - just include all attributes, used by pppd to dictionary.

I attached dictionaries for pppd and microsoft attributes.
To include it, please add this to /etc/radiusclient-ng/dictionary:

INCLUDE dictionary.pppd
INCLUDE dictionary.microsoft

Patch attached.
