The trick you found earlier doesn't work?

http://stackoverflow.com/questions/28615850/internet-explorer-11-replaces-authorization-header

Also, what if in keycloak.js if kc.clientSecret is null? Just remove
the client secret IMO. You shouldn't be exposing the client secret as
it is now public to everybody in the world....

I could find a solution for my IE problem.

IE overwrites the Authorization header in the XMLHttpRequest

(/protocol/openid-connect/token) with "Authorization: Negotiate".

To solve this problem, I added on the client the client_id

and client_secret to the form and changed the authorizeClient method, so

it checks first the form data instead of the authorization http header.

Have a look at my code:

https://github.com/gerbermichi/keycloak/commit/32880b210ed27f782a2f9fcd01da4df21ee0953c

Should I create a pull request for the changes or do you have a better

solution?

Hi Michael,

No idea if there is other solution, I've never tried SPNEGO with

Internet explorer TBH :(

Could you please create JIRA for this?

Thanks,

Marek

Hi all

My kerberos configuration works fine with FireFox and Chrome, but it

does not work with IE.

It shows a prompt where the user has to enter a username and password.

I can successfully get an access code, but I can not get an access

token, because IE overwrites the Authorization header in the AJAX

request. (see

http://stackoverflow.com/questions/28615850/internet-explorer-11-replaces-authorization-header)

I can fix this by adding

document.execCommand('ClearAuthenticationCache', 'false');

above of

var req = new XMLHttpRequest();

approximately at the line 374 in the keycloack.js file.

Is there another solution for this problem?

cheers

Michael
