Are you ready to discover one of the most hidden and underestimated Windows 2012 R2 features called "Work Folders"? Work Folders allows you to leverage your investment in File Servers while simultaneously providing end users with anywhere access to their data from their work PC as well as their personal devices. In this session, you will learn about the challenges to securely implement and manage "traditional" home folders to the BYOD (bring your own device) world. Learn how to deploy and manage Work Folders servers and clients, gain an understanding of how Work Folders operates end-to-end and integrates into your existing infrastructure, and how Work Folders takes advantage of capabilities like multi-factor authentication, Workplace Join and Selective Wipe to ensure that corporate data remains secure wherever it goes.

enabling access to data in offline scenarios, along
the lines of Citrix ShareFile , Onedrive for Business
and Dropbox, but without the cloud and sharing
features.“

14. Step 1
• Install Work Folders Role
Step 2
• Configure Work Folders Server with SSL
Step 3
• Configure the Work Folders Server for ADFS Authentication
Step 4
• Setting the Relying Party settings in ADFS
Step 5
• Configure the Web Application Proxy
Step 6
• Create the necessary DNS records

15. netsh http add sslcert ipport=0.0.0.0:443 certhash=<Cert thumbprint>
appid={CE66697B-3AA0-49D1-BDBD-A25C8359FD5D} certstorename=My

16.  In order to publish Work Folders with Web Application Proxy, it must use AD FS (OAuth2)
authentication instead of Windows Authentication.
 You can use PowerShell to configure the Work Folder Server for AD FS authentication using the
following command: Set-SyncServerSettings -ADFSUrl <AD FS URL>

17. $ECSIdentifier = "https://Windows-Server-Work-Folders/V1";
$ECSDisplayName = "EnterpriseClientSync";
$TransformRuleString = '@RuleTemplate = "LdapClaims" @RuleName = "Ldap" c:[Type ==
"http://schemas.microsoft.com/ws/2008/06/identity/claims/windowsaccountname", Issuer
== "AD AUTHORITY"] => issue(store = "Active Directory", types =
("http://schemas.xmlsoap.org/ws/2005/05/identity/claims/upn",
"http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name",
"http://schemas.xmlsoap.org/ws/2005/05/identity/claims/surname",
"http://schemas.xmlsoap.org/ws/2005/05/identity/claims/givenname"), query =
";userPrincipalName,displayName,sn,givenName;{0}", param = c.Value);' ;
$AuthorizationRuleString = '@RuleTemplate = "AllowAllAuthzRule" => issue(Type =
"http://schemas.microsoft.com/authorization/claims/permit",Value = "true");' ;
Add-ADFSRelyingPartyTrust -Identifier $ECSIdentifier -Name $ECSDisplayName -
IssuanceTransformRules $TransformRuleString -IssuanceAuthorizationRules
$AuthorizationRuleString -EncryptClaims:$false -EnableJWT:$true -AllowedClientTypes
Public;
The Relying Party settings must include the UPN in the claims since the Work Folders will use it to
impersonate as the user. Unfortunately there is no such file, we used a PowerShell script to create the
RP.
