Howto know if we are in Forms or Windows authentication mode ?

[WT]

Hello,

I tryed to fix a variable with the current authentication mode,
I tryed to use Request.LogonUs erIdentity AuthenticationT ype for this but
when I traced with this code
if (Request.LogonU serIdentity != null)
{
sb.AppendFormat ("Request.Logon UserIdentity AuthenticationT ype: {0}<br />",
Request.LogonUs erIdentity.Auth enticationType) ;
.....

I get nothing in my stringbuilder ???
Is it normal ?

Should I read web.config ?

Thanks for help

Hi WT,

As for the Requeste.IsAuth enticated or Request.Authent icationType, they're
just the same like the
HttpContext.Cur rent.User.Ident ity.Authenticat ionType(IsAuthe nticated ).
They actually represent the authentication type performed by the IIS web
server, such as "NTML" or "Negotiate" ..... rather than the authenticatio
setting of ASP.NET <authenticati on mode/>.

for your scenario, if you want to check the ASP.NET application's current
authentication mode, you can consider the following means:

1. Load the <authenticati on modesetting from application's web.config
file. You can use the WebConfiguratio nManager class to load applicationo
configuration settings. Also, for performance consideration, you can load
this setting into a class static property at application's startup time(or
at the first time the property is requested) so as to avoid multiple
accessing to the web.config file.

2. You can check the Context.User.Id entity's type, for windows
authentication, it is of "WindowsIdentit y" type while for
FormsAuthentica tion, it could be a FormsIdentity or GenericIdentity type.

Hope this helps.

Sincerely,

Steven Cheng
