User profile synchronization problem

This morning I was told that some people's profiles were showing old data in SharePoint.

Ooops! What does that mean: Profiles are not synchronized with Active Directory.

 I immediately checked the Central Administration > Operations > Timer Job Definitions for  profile sync, and saw that the jobs were hourly (by default) and they were all succeeding...

So I did a full import and it worked, the profiles started to show the new-correct data. 

I scheduled the full import to be run every evening.

I know this is not a complete solution but a workaround, but sometimes you have to solve it quickly :)
