Hi Aleksander,
Please advise regarding this. From the logs I can see that if "allowed-auth=pap|chap" then CHAP is tried first. But if that fails then who will try PAP? Is this modemmanager's responsibility or modem shall do it internally? Basically, I'm finding that if APN supports "PAP Only" authentication then "allowed-auth=pap|chap" does not connect and returns error. It works fine if "allowed-auth=pap" (I'm trying with MM 1.18.8 & EM7565 in MBIM mode) Thanks Amol From: Amol Lad Sent: Wednesday, 29 June 2022 11:19 AM To: ModemManager (development) <modemmanager-devel@lists.freedesktop.org> Subject: APN Authentication: allowed-auth=pap|chap Hi, An APN support "PAP" authentication with a username and password. In mmcli -simple-connect, we can specify "allowed-auth", key/value pair. I'm finding that if "allowed-auth=pap" then APN connects OK but if "allowed-auth=pap|chap", following error is returned: info 2022-06-29T03:51:34+00:00 : <info> [modem0] state changed (registered -> connecting) warning 2022-06-29T03:51:36+00:00 : <warn> [modem0/bearer1] connection attempt #1 failed: InvalidUserNamePwd Please advise if "allowed-auth=pap|chap" is supposed to work or passing multiple authentication type has some other significance? I am under the impression that if APN supports PAP then allowed-auth=pap|chap should also work Amol
