Explanation:
To configure your AD FS farm to authenticate users from an LDAP directory, you can complete the following steps:
Step 1: New-AdfsLdapServerConnection
First, configure a connection to your LDAP directory using the New-AdfsLdapServerConnection cmdlet:
$DirectoryCred = Get-Credential
$vendorDirectory = New-AdfsLdapServerConnection –HostName dirserver –Port 50000 –SslMode None –
AuthenticationMethod Basic –Credential $DirectoryCred
Step 2 (optional):
Next, you can perform the optional step of mapping LDAP attributes to the existing AD FS claims using the
New-AdfsLdapAttributeToClaimMapping cmdlet.
Step 3: Add-AdfsLocalClaimsProviderTrust
Finally, you must register the LDAP store with AD FS as a local claims provider trust using the AddAdfsLocalClaimsProviderTrust cmdlet:
Add-AdfsLocalClaimsProviderTrust –Name “Vendors” –Identifier “urn:vendors” –Type L
