LDAP-summary

This repository contains useful shell scripts to make interacting with LDAP/AD from the command line more pleasant.

The shell scripts provide easy access to the most common types of information that we've needed on users/groups at the DKFZ. They are made available here in the spirit of making every admin's life easier. The scripts are wrappers around ldapsearch by the OpenLDAP project.

Configuration

The scripts load their LDAP configuration from a separate config file: ldap-summary.conf, located in $XDG_CONFIG_HOME (by default: $HOME/.config/). An example config file is provided as ldap-summary.conf.template, which contains dummy values for all required settings.

Examples

analyse groups

Analyse a group or groups: who is in it, whose account has expired, how much overlap?

# group-matrix group1 group2 group3...
USERS  FULL_NAME         STATUS  group1  group2  group3
user1  Randomuser, Sam   active          Y
user2  Randomuser, Jay   EXPIRED Y       Y       Y
user3  Randomuser, Beau  active  Y
user4  Randomuser, Alex  active  Y       Y

recursively find ALL groups of a user

This finds all groups of a user, including those that they are only indirectly a member of.
