All your existing userID, password validation, and roles/rights assignments you coded in PowerBuilder will be carried over to the clients (both Windows client and mobile device).

In addition, we provide hooks to LDAP if you want to centralize things across multiple apps.

For more complex requirements, you can use  Visual Guard (www.visual-guard.com):

• Single Sign-on (SSO),
• Identity Federation,
• Multi-tenant applications,
• SaaS Application Security
• Supporting multiple type of users accounts
• etc.
