This week my friend Patrik Sundqvist<\/a> and I delivered a Service Manager event together with Microsoft in Sweden. There were a lot of good questions from the audience and a great interest in the product. One of the questions was if the Active Directory synchronize blank attributes from Active Directory if there is a value in the CMDB. Of course we have tried this in a sandbox J<\/p>\n

1. I created a new user account in Active Directory. I did not change any default values so the Office attribute (PhysicalDeliveryOfficeName) was set to < Not Set >
\n2. I ran the Active Directory connector synchronization
\n3. I verified that I had a blank Office attribute in the CMDB
\n4. I updated the attribute in the CMDB
\n5. I logged in and out with the account on a workstation
\n6. I ran the Active Directory connector synchronization
\n7. The Office attribute in the CMDB is back to blank<\/p>\n

If my AD user object is updated, in this case some attributes was updated when the user loged into a workstation, the watermark on the user object is updated, then the whole user will be synchronized back to the CMDB.<\/p>\n

Remember this! What you see is not always what you think in Service Manager. You might think that looking at a computer in the computer form is in fact looking at a single object in the CMDB. This is seldom the truth since most forms in Service Manager targets TypeProjections (which could be seen as a view displaying data from several objects related to each other). As an example you might take a look at the type projection acting as source to the \u00e2\u20ac\u0153computer form\u00e2\u20ac\u009d in Service Manager. As you can see in the definition below, quite a few different objects support the computer form.<\/p>\n

A short summary of this is \u00e2\u20ac\u009dlast-write wins\u00e2\u20ac\u009d and that you should be very aware that a form can be a mix of the result of a number of connectors and synchronized data.<\/p>\n","protected":false},"excerpt":{"rendered":"
