Hi I have an application that requires digital certificate. Each user has a certificate. Can a Windows 2003 XenApp 4.5 Server have multiple certs for the one app??? Ive never worked with certs before. Are the certs User based? How would a user select their cert? Would users have access to install the cert or would I need to do it on their behalf? Is there any best practices in relation to installing certs? Thanks Ang
