PROGRAM PURPOSE:

It’s easy enough for anybody to extract data from an LDAP directory, but
trying to sort that data in a useful way is often hampered by not being
able to sort by object context / container. This program reverses the
order of an object’s RDN giving you a field that can be used to sort
a mass of data in to container (OU) order:-

e.g.

	cn=employee1.ou=finance.o=novell
	cn=employee2.ou=student.ou=finance.o=novell 
	cn=employee3.ou=finance.o=novell
	cn=employee4.ou=IT.o=novell
	cn=employee5.ou=finance.o=novell
	cn=employee6.ou=student.ou=finance.o=novell 

Can be sorted in to:

	o=novell.ou=finance.cn=employee1
	o=novell.ou=finance.cn=employee3
	o=novell.ou=finance.cn=employee5
	o=novell.ou=finance.ou=student.cn=employee2
	o=novell.ou=finance.ou=student.cn=employee6
	o=novell.ou=IT.cn=employee4

PROGRAM REQUIREMENTS:

The input file must be a Comma Separated Values formatted file.

This program will only work where the input file contains one record
per line.

If RDN components are separated by ‘,’ then RDN MUST be enclosed in
quotes in the input file.

Any Header line must be separated with ‘,’ and have NO Quoted fields
or special characters.

This program should work with output from any LDAP compliant database,
including eDirectory, Active Directory etc; but it has only been
tested with LDAP output from eDirectory.

The program has been tested on SUSE Linux 10 on x86 using Perl v5.8.8
and on MS Windows 2000 SP4 using ActivePerl v5.8.8. It should
run on most Linux/Unix/Windows platforms with Perl v5.6 and
above.

RELEASE NOTES:

The program can deal with RDNs formatted with ‘,’ or with ‘.’ or a
mixture of both BUT the outputted RDN and reverse RDN will all
be formatted the same way, depending on how you answered the
pre-run questions.

The program can deal with a mix of non-quotation enclosed and quotation
enclosed data fields.

The program detects which operating system it is running on.

If the host OS is Linux you will be given the option to write the output
using Linux or Windows line termination.

The program can accept a file with lines terminated by carriage-
return+newline (ascii 13 & 10) or with just newline (ascii 10)
or a mixture of both.

The program can also be used simply to change the formatting of an RDN
from ‘.’ to ‘,’ or vice-versa.

This program DOES NOT work against LDIF files.

Any special characters in the RDN may invalidate the output.

The program does not work with multi-line fields (such as the LDAP
exported Login Script attribute).

The resulting reverse RDN will always be enclosed in quotes.

PROGRAM QUESTIONS:

  • Name of input file [Default=ldapinput.csv]:
    ldapinput.csv (lower-case on Linux/Unix).
  • Name of output file [Default=ldapoutput.csv]:
    By default the program will write to an output file called
    ldapoutput.csv (lower-case on Linux/Unix). The output file
    WILL BE OVER-WRITTEN if it already exists!
  • What is the number of the RDN/OID field:
    If you are not sure which field contains the RDN then open your
    CSV file in a spread-sheet program and count the columns (e.g.
    If the RDN is in column ‘I’ then it’s field number is 9).
  • Start lines to ignore (Headings etc.) [Default=0]:
    Are there any non-data lines in the csv file? Such as a header
    line and data-empty lines?
  • Fix Header Line 1 (Y/N)? [Default=N]:
    If you answered 1 or more to the previous question then you will
    be prompted with this question. If you choose ‘Y’ to ‘Fix’ the
    header line, then the header line will be altered to include a
    heading for the ‘Reverse RDN’ field.
  • (A)dd ReverseRDN or (R)eplace RDN [Default=A]:
    If you choose ‘A’ a column containing the ‘Reverse RDN’ will be
    added to the output file. If you choose ‘R’ then in the output
    file the RDN field will be replaced with the ‘Reverse RDN’ field.
  • Is The RDN Separator a ‘,’ or a ‘.’ [Default=',']:
    You need to tell the program how the RDNs in the input csv file
    are formatted. Are they true LDAP format (using a ‘,’) or
    eDirectory style (using a ‘.’)?
  • Output RDN separator ‘,’ or ‘.’ [Default=',']:
    You have the option as to how the output RDN and Reverse RDN will
    be formatted.
  • Terminate output lines with (W)indows Style or (L)inux style [Default=L]:
    You will only be given this option if the program is running
    on a non-Windows machine. If you choose ‘W’ output lines will
    be terminated by carriage return+newline (ascii 13 & 10). If
    you choose ‘L’ then output lines will be terminated with
    newline (ascii 10) only.
