Couple of things.

• if you have the User Profile Service enabled then setup a filer to exclude the disable /deleted account from importing.Creating User Profile Synchronization Exclusion Filters using the userAccountControl attribute
• If you want to remove the user from sharepoint then i recommend to use this powershell script.

Funcations:

 Function RemoveUser($LoginName,$SiteUrl) { #Get site $Site = Get-SPSite | where {$_.url -eq $SiteUrl} If($Site) { $Web = $Site.openweb() Try { #Get user $user = $web.SiteUsers | where {$_.UserLogin -like "*$LoginName"} #Remove user if($user) { $web.SiteUsers.Remove($user) write-host "Remove user $LoginName from site '$SiteUrl' successfully." } Else { write-Warning "User $LoginName not found on site '$SiteUrl'." } } Catch { Write-Error $_ } } } 

then run the command like this:

 RemoveuserFromwebapplication.ps1 -LoginName "user1" -SiteUrl "http://win-chu4c2rckti:8080/sites/project"
