[Fedora-directory-users] Schema Conversion

hi,

i've updated my perl script to do RFC 2252 ordering as well as
formatting.  Steven Bonneville (RedHat) brought it to my attention that
RHDS/FDS was very strict about following the RFC while OpenLDAP was not.
~ so, if an OL schema was out of order, it caused problems when being
converted to RHDS/FDS.

anyway, i've attached my script.  it should also be useful for
reordering already converted schemas just in case the order might not be
correct.

i hope everyone finds it useful, please let me know how it works out.

thanks,
nathan

| DC / list,
|
| i have a quick and dirty perl script i had cooked up to do this.  it was
| enough to allow me to convert some openldap schema to FDS.  i was able
| to successfully start FDS after converting a few of them (samba3, etc).
|
| i probably went about it all wrong.  for instance the dn: line is
| probably written out incorrectly (i just did what i could to make it
| work).  i haven't even tried importing a database using the newly
| converted schemas, so your milage will almost certainly vary.
|
| anyway, i've pasted it in the message below because i'm not sure if the
| list allows attachments.  i hope it's of some use to people trying to
| make the switch from openldap to FDS.
