length of value_pair value is only 127

I have to process a vendor specific attribute from cisco, i.e. the
Cisco-SSG-Account-Info attribute.

#define CISCO2ATTR(x) ((9 << 16) | (x))
vp = pairfind(request->packet->vps, CISCO2ATTR(PW_SSG_ACCOUNT_INFO));
if (!vp) {
   radlog(L_INFO, "Value pair not found!");
   radlog(L_INFO, "%s, %i", vp->vp_strvalue, strlen(vp->vp_strvalue));
If I send an authentication request the attribute is found. The problem is
that the vp->vp_strvalue is cut after 128 chars and
strlen(vp->vp_strvalue)) is 127. Though the length of vp_strvalue is
defined in libradius.h by MAX_STRING_LEN (0-253 octets) according to RFC.

I have sent the request by the NTRadPing test utility.

Is it a known issue? Thank you for help.
