Estimating NTDS.dit size increase for Credential Roaming

-

i found thread estimating size increase in the ntds.dit file after enabling credential roaming:

http://blogs.technet.com/b/instan/archive/2009/05/26/considerations-for-implementing-credential-roaming.aspx

it provides formula: (((certificatesizeinbyte + keysizeinbyte) * (#usercertificates * #pastcertificaterenewals * #machines) + (dpapikey * profileageinyears * 4) + dpapipreferredfile + (#storedusernamesandpasswords * 400)) / 1024

however, since published hotfix released decrease database size:

http://support.microsoft.com/kb/2520487

i'm wondering how calculate impact of credential roaming on ntds.dit file after applying hotfix.

thanks

hi,

posting in microsoft technet forums.

can see in kb2520487, hotfix enables credential roaming filter user credentials before uploads them. prevents addition of unnecessary credential information/impact on ad ds database. means issue mentioned in blog fixed hotfix. 

please feel free let know if have further question or concern.

regards

kevin
