Profile Management addresses user profile deficiencies in environments where simultaneous domain logons by the same user introduce complexities and consistency issues to the profile. For example, if a user starts sessions to two different virtual resources based on a roaming profile, the profile of the session that terminates last overrides the profile of the first session. This problem, known as "last write wins", discards any personalization settings that the user makes in the first session.
You can tackle the
problem by using separate profiles for each resource silo. However, this
results in increased administration overhead and storage capacity requirements.
Another drawback is that users will experience different settings depending on
the resource silo they access.
Profile Management optimizes profiles in an easy and reliable way. At interim stages and at logoff, registry changes, as well as files and folders in the profile, are saved to the user store for each user. If, as is common, a file already exists, it is overwritten if it has an earlier time stamp.
At logon, users'
registry entries and files are copied from the user store. If a locally cached
profile exists, the two sets are synchronized. This makes all settings for all
applications and silos available during the session and it is no longer
necessary to maintain a separate user profile for each silo. Citrix streamed
user profiles can further enhance logon times.
Profile Management helps to safeguard application settings for mobile users who experience network disruption (if the offline profiles features is configured) and users who access resources from different operating systems (if the cross-platform settings feature is configured).
Note: Profile Management processes domain user logons not local accounts.
