Is there any limitation to the proxy authentication support of rhn_register?
The proxy of the network I'm on sends the follow 407:
HTTP/1.1 407 Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request. Access to the Web Proxy filter is denied. ) Via: 1.1 VANESSA Proxy-Authenticate: Negotiate Proxy-Authenticate: Kerberos Proxy-Authenticate: NTLM
It seems that rhn_register is not able to any of the authentication schemes above.
