Sync User Information List

If you use the SharePoint in the Domain, you may connect to AD, use it as your User Profile Source. And the MOSS would import the data from the AD, which there is a profile database in the database. You can configure the SSP to do the AD sync configuration.

But when you first login into a site collection, the site collection would record your information into a list called User Information List. You can not see this list form the browser. You can use the sharepoint designer to see it.

When your information changed in the AD, and imported into the Profile Database, the information in the User Information List does not change. For example, your Display Name is Fox Mulder, after you visit the site collection, the Created By column of items in this site collection would be Fox Mulder. After you change your display name to Fox Clinton in AD, and do the import work again. the column is still Fox Mulder.Because the User Information List did not do the sync work with the Profile database.There is a command  to solve this problem:

stsadm -o sync -deleteolddatabases 0

After you run this command, you should wait for some time. It's not real time. There is a timer service to do the work.
