User Profile Sync and Offline Content Databases
by liquidpooled on Nov.10, 2009, under Microsoft, Office, Sharepoint Server
After a recent farm migration, a number of content databases were left offline. This had the unintended consequence of not allowing user profile synchronization to occur across site collections (where the content databases were offline).
The quick fix? Bring the content database(s) online.
The moral of the story? Do not leave your content database(s) offline without a good reason. If you do leave them offline, User Information Lists in the offline site collections will not be synchronized with the SSP.
