Authentication is only defined at the Web Application level, and the only valid auth methods are Classic (Windows (Basic/NTLM/Kerberos)), Claims (Windows (Basic/NTLM/Kerberos)), FBA Claims, , SAML Claims (ADFS), and Anonymous.
You can find out what authentication scheme(s) are enabled via:
$wa = Get-SPWebApplication http://webApp1$wa.IisSettings["Default"] #replace with the zone name you're interested in
The output will look similar to this:
PS C:\Users\trevor> $wa.IisSettings["Default"]
AuthenticationMode : Forms
MembershipProvider : i
RoleManager : c
AllowAnonymous : False
EnableClientIntegration : True
ServerBindings : {Microsoft.SharePoint.Admini
stration.SPServerBinding}
SecureBindings : {}
UseWindowsIntegratedAuthentication : True
UseBasicAuthentication : False
DisableKerberos : True
ServerComment : SharePoint
Path : C:\inetpub\wwwroot\wss\Virtu
alDirectories\spwebapp180
PreferredInstanceId : 42768054
UseClaimsAuthentication : True
ClaimsAuthenticationRedirectionUrl :
UseFormsClaimsAuthenticationProvider : False
FormsClaimsAuthenticationProvider :
UseTrustedClaimsAuthenticationProvider : False
UseWindowsClaimsAuthenticationProvider : True
OnlyUseWindowsClaimsAuthenticationProvider : True
WindowsClaimsAuthenticationProvider : Microsoft.SharePoint.Adminis
tration.SPWindowsAuthenticat
ionProvider
ClaimsAuthenticationProviders : {Windows Authentication}
ClaimsProviders : {}
ClientObjectModelRequiresUseRemoteAPIsPermission : True
UpgradedPersistedProperties : {}
So on this Web Application in the Default Zone you can tell I have Windows Claims enabled, not using Kerberos (so using NTLM), and Trusted (SAML/ADFS) is not enabled, neither is Forms or Anonymous.
