A script for importing Exchange flatfiles to LDAP

These scripts were used in a migration from Exchange to Google Apps (Gmail). Flatfiles were exported from Exchange (powershell scripts available near these) and imported to LDAP. A separate sync happens from LDAP to Google.

These scripts were made as a one-off solution and will likely require a lot of hacking to be of use to others.

  • For syntax help, please run "python LCI_main.py --help"
  • Logs to INFO+ stdout and DEBUG+ LCI.log by default
  • Requires python-ldap
  • You should be able to enter your LDAP settings to local_LCI_settings.py

Running the import

It is recommended to run the migrations in this order:
  • aliases.txt, mailcontacts.txt, DGs.csv

  • Currently three types of flatfiles are supported:

    1. alias.txt (Aliases)

    To import: python LCI_main.py --aliases data/aliases.txt

--8<-- (example input) DisplayName : Aarne Bertta PrimarySmtpAddress : [email protected] EmailAddresses : {[email protected], [email protected]}

--8<--

  1. mailcontacts.txt (External mails)

To import: python LCI_main.py --mailcontacts data/mailcontacts.txt

--8<-- (example input) DisplayName : Aarne Asiakas PrimarySmtpAddress : [email protected] ExternalEmailAddress : SMTP:[email protected] EmailAddresses : [email protected] --8<--

  1. DGs.csv (Distribution groups)

To import: python LCI_main.py --distributiongroups data/DGs.csv

--8<-- (example input) "[email protected]","[email protected]","[email protected]","[email protected]","zumba-club","[email protected]" "[email protected]","[email protected]","[email protected]","[email protected]","zumba-club","[email protected]" --8<--

Re-running the import (running the migrations again)

  1. Run --aliases normally
  2. Run --mailcontacts normally (new ones will be added, diff for changes in existing mailcontacts)
  3. (!) Run --removedistributiongroups for the _previous_ DGs.csv
  4. Run --distributiongroups for the new DGs.csv
