Is it safe using NameSpaceType value for ADFS authentication with SSO?

Hi,

I am developing a java application to authenticate users with ADFS to support SSO. When i make a call to https://login.microsoftonline.com/GetUserRealm.srf to get the user information, the response is as follows:

<RealmInfo Success="true"><State>3</State><UserState>2</UserState><Login>adapterDev@infaawcrm.com</Login><NameSpaceType>Federated</NameSpaceType><DomainName>INFAAWCRM.COM</DomainName><FederationGlobalVersion>-1</FederationGlobalVersion><AuthURL>https://infaawccrm.infaawcrm.com/adfs/ls/</AuthURL><IsFederatedNS>true</IsFederatedNS><STSAuthURL>https://infaawccrm.infaawcrm.com/adfs/services/trust/2005/usernamemixed</STSAuthURL><FederationTier>0</FederationTier><FederationBrandName>INFAAWCRM.COM</FederationBrandName><AllowFedUsersWLIDSignIn>false</AllowFedUsersWLIDSignIn><Certificate>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</Certificate><MEXURL>https://infaawccrm.infaawcrm.com/adfs/services/trust/mex</MEXURL><SAML_AuthURL></SAML_AuthURL><PreferredProtocol>1</PreferredProtocol><EDUDomainFlags>0</EDUDomainFlags></RealmInfo>

I wanted to know, is it safe to use NameSpaceType or IsFederatedNS tags to decide between an online user and an Active Directory user? 

Please Suggest.

Thanks
