This CLI tool allows you to easily perform basic operations (changes) on your LDAP server. It's aimed to ease these kind of tasks, without having to, necessarily, deal with LDIF files. Moreover, it permits you to do some of these things, in bulk!.

More precisely, this program, allows you to:

• Modify LDAP attributes (replace, add and delete modes, are supported!).
• Delete LDAP entries.
• Add LDAP entries with their corresponding attributes, by importing them from a CSV file!.
• Query the LDAP attributes of a particular entry, based on its DN.

At present, there are some features that I've planned, that aren't yet implemented. Hopefully, I'll do so in future releases!.

This is what it needs, in order to work:

• Python 3
• python-ldap library (tested with v3.2.0).

I don't take any responsibility on the consequences of the usage of this program!. Use it at your own risk!!.

It's advisable to always have a working backup of your LDAP database, prior to ANY modification!.

The recommended way to install this program, is by using pip:

pip install tiny-ldap-manager

To start with, here's the help output:

usage: tiny-ldap-manager [-h] [-v] SERVER BINDDN {ls,modify,add,delete} ...

Easily perform several LDAP operations

positional arguments:
  SERVER                URI formatted address of the LDAP server
  BINDDN                DN of the user to bind the LDAP server
  {ls,modify,add,delete}
    ls                  List LDAP attributes for specified DN
    modify              Modify an LDAP attribute
    add                 Add LDAP entries from a CSV file
    delete              Delete an LDAP entry

optional arguments:
  -h, --help            show this help message and exit
  -v, --version         Show current version

The basic syntax you've to respect is the following:

tiny-ldap-manager [SERVER] [BINDDN] [ACTION] [ARGUMENTS]

In order of appearance:

• [SERVER] belongs to the URI formatted address of your LDAP server. This argument is mandatory!.
• [BINDDN] is the DN ("Distinguished Name") of the LDAP user with permissions for the operation you wish to perform!. It's a mandatory argument!.
• [ACTION] is the actual operation you want to perform. At present, there are four valid operations you can use: ls, modify, add or delete. This argument is also mandatory and you must provide ONLY one of them!. Please, see below for more details.
• [ARGUMENTS]: when you perform an [ACTION], any of them requires, at least, one or more additional arguments. You can add the --help argument to any of them, for specific details. Please, see below for more on this.

Take into account that, an authenticated session is always assumed. So you are gonna be asked for the corresponding credentials, each time you perform an operation!.

The ls action, allows you to quickly see the attributes of a particular LDAP entry. For this, you have to provide the DN of the latter. For example:

tiny-ldap-manager ldap://192.168.100.5 "cn=config" ls "uid=joe,ou=people,dc=somecorp,dc=com"

For modifying or adding an attribute to an LDAP entry, you logically use the modify action. There are three types of modifications possible to use:

• REPLACE is to be used whenever you want to modify the value of an existing attribute. This is the mode used by default!.
• ADD is for adding a non-existing attribute!.
• DELETE is, of course, for deleting an existing attribute!.

If you don't provide any additional arguments, the REPLACE mode is used by default!. The complete syntax for it, is:

tiny-ldap-manager [SERVER] [USERDN] modify [ATTRIBUTE] [VALUE] 

Where [ATTRIBUTE] is the name of the attribute you want to modify, and [VALUE] is the new value for that attribute!.

Let's see an example:

tiny-ldap-manager ldap://192.168.100.5 "cn=config" modify "uid=joe,ou=people,dc=somecorp,dc=com" telephoneNumber "5555" 

Above, we're modifying the existing telephoneNumber attribute with a new value of5555.

Make sure that the new value for the attribute you're modifying, is NOT the same as its current value!. Otherwise, you'll get an error!.

In order to use a different mode for making a modification, you've to do it using the -M argument, as follows:

tiny-ldap-manager ldap://192.168.100.5 "cn=config" modify -M ADD "uid=willy,ou=people,dc=somecorp,dc=com" telephoneNumber "8006666"

With this latter example, we add the telephoneNumber attribute, with its corresponding value.

It's important to note that this program is case-sensitive, so the modification mode always goes with capital letters!.

Finally, an example for using the DELETE mode, for removing an existing LDAP attribute:

tiny-ldap-manager ldap://192.168.100.5 "cn=config" modify -M DELETE "uid=charles,ou=people,dc=somecorp,dc=com" telephoneNumber ""

Note that the double quotes at the end of the command, are necessary!.

The way to add entries to an LDAP database with tiny-ldap-manager, is by creating a CSV file using the header row (first row), to specify the attributes for each new entry. You must ensure that you use a semi-colon (;) as the CSV delimiter!.

Besides the CSV header row, the rest of them, are to be used to define the value of each corresponding attribute.

The order in which the LDAP attributes are specified in the CSV file, is not important, as long as there is a logical correlation between the value assigned to each attribute and the attribute itself!. Even then, for the sake of clarity, it's a good idea to always put the DN in the first place!.

Now, let's see an example of a CSV file content:

dn;objectClass;uid;cn;sn;givenName;displayName;mail
uid=cdarwin,ou=people,dc=scileague,dc=org;['inetOrgPerson','organizationalPerson'];cdarwin;cdarwin;Darwin;Charles;Charles Darwin;charlesdarwin@scileague.org
uid=alovelace,ou=people,dc=scileague,dc=org;inetOrgPerson;alovelace;alovelace;Lovelace;Ada;Ada Lovelace;adalovelace@scileague.org
uid=aeinstein,ou=people,dc=scileague,dc=org;inetOrgPerson;aeinstein;aeinstein;Einstein;Albert;Albert Einstein;alberteinstein@scileague.org

The following is how you would import such entries:

tiny-ldap-manager ldap://192.168.100.5 "cn=config" add scileague.csv

As you might noticed in the CSV, the entry that belongs to Charles Darwin, has a formatted list of values for the objectClass attribute. That's a supported way to include more than one value for a given attribute.

As a final note about importing new LDAP entries, if one or many of them, already exist in the LDAP database, you can be sure that they won't be imported, but equally important, is the fact that they won't interrupt the whole process neither. An output message is shown in each case.

You can simply remove an LDAP entry from your database, by indicating its DN, as is shown next:

tiny-ldap-manager ldap://192.168.100.5 "cn=config" delete "uid=bob,ou=people,dc=somecorp,dc=com"

Poor Bob!. :)
