After running the step "Create a form-based Security Token Service site" of guide "Deploy an Enterprise Portal site that uses forms-based authentication [AX 2012]" we create provider with Add-AXSharepointClaimsAuthenticationProvider.
The problem we sometimes have that signing url which will assign to this provider will look like http://machine_name.fqdn:port/_layouts/<provider name>/Login.aspx (i.e. http://dax2012.contoso.com:7000/_layouts/FormsAuth/Logis.aspx ) which is OK, but not when we want to use host headers. So we get quite often the request how the sign url can be change. We can do it using SharePoint Power Shell command Set-SPTrustedIdentityTokenIssuer:
Set-SPTrustedIdentityTokenIssuer -SignInUrl https://sign.contoso.com:443/_Layouts/FormsAuth/Login.aspx -Identity FormsAuth -ImportTrusCertificate <path to signing certificate .cer file>
When I do this I get the following message from accessing the site and entering the FBA username and password
error 405 with programming and the url is:
Any ideas on how to fix this?
There can be the issue with signing certificate you need to look into Application event log on SharePoint server to get more info
