    Bug Description: Perl errors when running migrate-ds-admin.pl
    Reviewed by: nkinder, nhosoi (Thanks!)
    Branch: master
    Fix Description: We may not have a single $admininf object if there is a
    skin package, so get the first value from the list of Inf objects.  Added
    a new function getInfsVal to get the value from a list of Inf objects
    given a section and a parameter.
    30updateglobalprefs was using the wrong map - we don't need the configds
    map if we're just doing updates.
    during migration ConfigDirectoryAdminID can be just a userid - do not
    assume it will always be a DN
    Had to amend my previous patch - ConfigDirectoryAdminID was not being set
    Platforms tested: Fedora 15 x86_64
    Flag Day: no
