# Convert OpenLDAP schema files into Fedora DS format with RFC2252 compliant printing
|
|
#
|
|
# First Release : Mike Jackson <mj@sci.fi> 14 June 2005
|
|
# http://www.netauth.com/~jacksonm/ldap/ol-schema-migrate.pl
|
|
# Professional LDAP consulting for large and small projects
|
|
#
|
|
# - 6 Dec 2005
|
|
# - objectclass element ordering
|
|
#
|
|
# Second Release : Alyseo <info@alyseo.com> 05 Februrary 2006
|

# http://www.alyseo.com/
|
|
#
|
|
# - 05 Februrary 2006
|
|
# - parsing improvement to accept non-RFC compliant schemas (like ISPMAN)
|
|
# - adding RFC element : Usage, No-user-modification, collective keywords
|
|
# - 08 Februrary 2006
|
|
# - adding help & usage
|
|
# - now this script can also beautify your schemas: "-b"
|
|
# - count attributes and objects class: "-c"
|
|
# - display items that can not be converted (empty OID...): "-d"
|
|
# - 15 February 2006
|
|
# - adding workaround for Fedora DS bug 181465:
|
|
# https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=181465
|
|
# - adding duplicated OID check: "-d"
|
|
# Useful to manually correct nasty schemas like:
