[Serusers] New known problems with radius_auth module

[Bjoern Zuelch]

Hi all,

i have found some probs with the radius_auth module in ser.
the ane in the function authorize() in file authorize.c :

when calling the function check_nonce this function returns always that the
two nonce's (given and new generated one are not the same. But if we compare
the two nonce's manually both are the same. I replaced the memcmp function
with the strcmp funtion,but nothings changes. So there is may a missing \0
at the end of the strings.

Next problem is in the function check_response:
On Solaris we have no freeradiusd ,so I replaced it through
radius_authorize(...).
If the function radius_authorize is called, the radiusmessage will be
created through calling the function rc_avpair_add(...). All is fine if it
will be standard radius-attributes. when the first sip-specific attribute is
comming the rc_avpair_add funtions returns -1. I followed this problem and
find out that in the radiusclient-lib. in function
rc_avpair_assign(avpair.c)/rc_avpair_new(avpair.c) only attributes of the
types PW_TYPE_STRING, PW_TYPE_DATE, PW_TYPE_INTEGER, PW_TYPE_IPADDR are
reccognised. If a PW_SIP_USER_ID attribute or other specific Sip attributes
will be added to the radiusmessage, this function returns with error message
"UNKNOWN ATTIBUTE TYPE" and no radius-authentification is done....
....
RADIUS: rc_avpair_new MALLOC erfolgreich
RADIUS: rc_avpair_assign type=0
RADIUS rc_avpair_assign result=0
RADIUS: rc_avpair_new unknown attribute 110
RADIUS: VALUEPAIR insert fehgeschlagen.!!!
check_cred(): returnvalue of radius_authorize()=-1
....
One possibility is that, I add the PW_SIP_* attributes to the radiusclient
and look, if it run.

The next Problem may be, that the radius server does not understand the sip
specific attributes, if we not use freeradius.
