i did the following search:


and found quite a lot existing threads about this message.

There seems to be a FAQ about this available in "No basic authentication headers were found" message which mentions some additional required web server configuration for specific web server modules which might include the one you are using:


Hi tom42,

Thank you for the reply. I am sorry for haven’t been done the search properly as you did.

I have tried the first solution from the link you provided. Namely, put the following line in the vhost file of my apache site.

SetEnvIf Authorization "(.*)" HTTP_AUTHORIZATION=$1

And it works!

Thank you!
