Re: Basic authentication fails probably because of Base64 enconding

[Thomas Raddatz <thomas.raddatz@xxxxxxxxxxx>]

Mirco,

Please check the content of your "username" field. When I decode the Base64 
string I get the following result:

00000000: 62 75 62 69 40 65 78 61 6d 70 6c 65 2e 6f 72 67 bubi@xxxxxxxxxxx
00000010: 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20
00000020: 20 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00  ...............
00000030: 00 00 3a                                        ..:

The colon is added by HTTPAPI but the blanks and NULL values must come from 
your "username" field:

Snippet from http_setauth():

   eval      wwString = %trimr(peUserName) + ':' +
                        %trimr(pePasswd)
   callp     http_xlate( %len(%trimr(wwString))
                       : wwString
                       : TO_ASCII )

   eval      wwEncLen = base64_encode(%addr(wwString):
                             %len(%trimr(wwString)):
                             %addr(wwEncoded):
                             %size(wwEncoded))


Thomas.
