User authentication via RADIUS/PAP no longer works in ntopng

Environment:

• OS name: Debian
• OS version: 11.7
• Architecture: amd64

  ntopng -V

  Version: 5.7.230510 [Enterprise/Professional build] GIT rev: dev:056dd000a30ad02a47c94bc652e852554cd2efe1:20230510 Pro rev: r5721 Built on: Debian GNU/Linux 11 (bullseye) System Id: Platform: x86_64 Edition: Enterprise L (Bundle) License Type: Permanent

What happened: Since an automatic update of ntopng about two weeks ago, authentication via RADIUS/PAP no longer works. The reason is that CHAP is used instead of PAP:

RADIUS Protocol Code: Access-Request (1) Packet identifier: 0xd3 (211) Length: 88 Authenticator: 53315c4c1e64bfd5d2152271bb22ce11 Attribute Value Pairs AVP: t=User-Name(1) l=5 val= Type: 1 Length: 5 User-Name: tgh AVP: t=CHAP-Challenge(60) l=32 val= Type: 60 Length: 32 CHAP-Challenge: AVP: t=CHAP-Password(3) l=19 val= Type: 3 Length: 19 CHAP-Password: CHAP Ident: 0x23 CHAP String: AVP: t=NAS-Port(5) l=6 val=0 Type: 5 Length: 6 NAS-Port: 0 AVP: t=NAS-IP-Address(4) l=6 val= Type: 4 Length: 6 NAS-IP-Address:
