# Example shell script showing how to parse LDIF output from the 
# ldapsearch command into a json array. Please note that this 
# script almost certainly does not handle every edge case, and 
# is best used to pull a handful of fields a user or group 
# record in a FreeIPA ldap server and format them as JSON for use
# in other tools.

The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

1. Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.)

git clone --bare [email protected]:usi-systems/easytrace.git
