## Convert an LDIF file containing sambaAccount entries

## Usage: convertSambaAccount --sid=<Domain SID> \
##       --input=<input ldif> --output=<output ldif> \
##       --changetype=[modify|add]
##
## You can generate an input ldif file using:
## $ ldapsearch -LL -x -h ldapsrv -D cn=root,dc=company,dc=com \
##   -b dc=copmany,dc=com > /tmp/samba3.alpha23.ldif
##
