Remove configuration custom STS with old web application using powershell ?

Question

HI
i configured a custom sts with sharepoint 2010 web application using following commands,
$cert = New-Object System.Security.Cryptography.X509Certificates.X509Certificate2("c:\signing.cer")
$map1 = New-SPClaimTypeMapping -IncomingClaimType "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/emailaddress" -IncomingClaimTypeDisplayName "EmailAddress" –SameAsIncoming
$map2=New-SPClaimTypeMapping -IncomingClaimType "http://schemas.microsoft.com/ws/2008/06/identity/claims/role" -IncomingClaimTypeDisplayName "Role" –SameAsIncoming
$realm=”http://claimauthweb/_trust/default.aspx”
$ap=New-SPTrustedIdentityTokenIssuer -Name "SimplePassiveSTS" -Description "A simple Asp.Net STS on DevBox." –Realm $realm -ClaimsMappings $map1,$map2 -ImportTrustCertificate $cert -SignInUrl "https://devbox/SimpleSTS/default.aspx" -IdentifierClaim $map1.InputClaimType
after that i create the new web application with claimauthweb and selected trusted identity provider. 
but when i create again new web application with different name and ip , after when i login to new web application using custom
sts it redirects to sts login page and after it goes to claimauthweb application not the new web application.
so here how i unregister with old web application and again register sts with new web applicatio?

I believe if you want to run this you will need to remove the provider from all Web Applications in CA. Then you should be able to run Remove-SPTrustedIdentityTokenIssuer.
