cfengine's regular expressions match the whole line; that is, as if
there were implicitly a ^ in front and a $ at the end of the line.  Your
regexp was probably meant to read
        LocateLineMatching "URI.*"

Also, this configuration fails if there isn't already a line starting
with `URI'.  The most elegant solution proposed so far seems to be

BeginGroupIfNoLineMatching "URI.*"
        Append "URI dummy"
# now we're sure a line URI exists...
ResetSearch "1"
LocateLineMatching "URI .*"
ReplaceLineWith "URI ldap://localhost/";
