Re: Schema Conversion

[Rich Megginson <rmeggins@xxxxxxxxxx>]

Thanks!  I've added a link to this script on the http://directory.fedora.redhat.com/wiki/Howto:OpenLDAPMigration page.

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).

And here is the one which I promised. It does OL schema to LDIF conversion, as well as pretty printing for readability.


usage: ./ol-schema-migrate.pl nis.schema > nis.ldif


Sorry, I couldn't think of a better name for the script. Let me know (on the list) if there are any problems with it and I'll fix them.
