Thanks in advance.

Answer 1

Thanks for the response.
My scenario is I am dynamically planning to get membership provider as I have to create token during forms authentication.
I found the answer
private static string GetFbaZoneUrl(SPWeb web)
{
string providerAndRole = null;
SPWebApplication webApp = web.Site.WebApplication;
foreach (var zone in webApp.IisSettings.Keys)
{
var settings = webApp.IisSettings[zone];
var fbaProvider = webApp.IisSettings[zone].FormsClaimsAuthenticationProvider;
if (fbaProvider != null)
{
// We found the zone on the web app where FBA is enabled.
// This is the zone whose URL we want.
// SPAlternateUrl fbaUrl = webApp.AlternateUrls.GetResponseUrl(zone, false);
providerAndRole = fbaProvider.MembershipProvider + "," + fbaProvider.RoleProvider;
break;
}
}
return providerAndRole;
}
Hope this code helps someone.
Thanks

This is quite easy , in CSOM get the current username (if you are logged in with a forms based account) .The username will be of the following format :
"i:0#.f|membership|someone.example.com"
The "i:0#.f|membership|someone.example.com" is the membership provider name. Use javascript substring function to get this section.
To get the current user loginname, use the following code which is also provided here
function GetCurrentUsername()
{
var ctxt = new SP.ClientContext.get_current();
this.website = ctxt.get_web();
this.currentUser = website.get_currentUser();
ctxt.load(currentUser);
ctxt.executeQueryAsync(Function.createDelegate(this, this.onSucceess), Function.createDelegate(this, this.onFail));
}
function onSucceess(sender, args)
{
alert(currentUser.get_loginName());
}
function onFail(sender, args)
{
alert('request failed ' + args.get_message() + '\n'+ args.get_stackTrace());
}
