Setup: if there is a dial in server using * mpd5 * external radius server in different jail (freeradius3) * MS-CHAPv2 for authentication (done by freeradius3) authentication succeeds, but mpd5 disconnects immediately because of alleged missing MS-CHAP2-Success attributes. Logging of mpd5 shows: mpd[10012]: [L_l2tp] RADIUS: Authenticating user 'username' mpd[10012]: [L_l2tp] RADIUS: Rec'd RAD_ACCESS_ACCEPT for user 'username' mpd[10012]: [L_l2tp] RADIUS: PANIC no MS-CHAP2-Success received from server! Checking this at freeradius3 server and packet capture show that the attrib= ute indeed exists but seems to be ignored by mpd5/libradius. Replacing libradius on log in server with pre-SA version makes mpd5 work ag= ain: mpd[96202]: [L_l2tp] RADIUS: Authenticating user 'user' mpd[96202]: [L_l2tp] RADIUS: Rec'd RAD_ACCESS_ACCEPT for user 'user' mpd[96202]: [L_l2tp] AUTH: RADIUS returned: authenticated mpd[96202]: [L_l2tp] CHAP: Auth return status: authenticated mpd[96202]: [L_l2tp] CHAP: Reply message: S=3DXXXXXXXX mpd[96202]: [L_l2tp] CHAP: sending SUCCESS #1 len: 46 I haven't found out which part of fix is to be blamed but this situation is rather unpleasant (especially since mpd5 is the main application of libradi= us). --=20 You are receiving this mail because: You are the assignee for the bug.=
