Some duplicate entries in /etc/services cause ldapadd to fail when running
migrate_all_*.pl with a "key already exists" error due to the fact that
two separate entries are created with different port numbers or names. Initially
reported in Bug 147804 but still a problem with FC5 + latest updates. The
following entry in /etc/services causes problems with port number:

echo 4/ddp

Additionally, also the following aliases also cause problems with names:

  CVSup
  NeXTStep

Uncommenting them all fixes the problems.

Please consider fixing.
