zabbix-ldap-sync -- Sync your Zabbix users with LDAP directory server

The zabbix-ldap-sync script is used for keeping your Zabbix users in sync with an LDAP directory server.

It can automatically import existing LDAP groups and users into Zabbix, thus making it easy for you to keep your Zabbix users in sync with LDAP.

Requirements

• Python 3.x.x
• pyldap
• pyzabbix
• docopt
• Zabbix 3.4

You also need to have your Zabbix Frontend configured to authenticate against an AD/LDAP directory server. (using http or ldap-auth)

Check the official documentation of Zabbix on how to configure Zabbix to authenticate against an AD/LDAP directory server.

Setup virtualenv

apt-get install python-dev virtualenv libpython3.*-dev libldap2-dev libsasl2-dev
virtualenv -p python3 venv
source venv/bin/activate
pip install -r requirements.txt

Configuration

In order to use the zabbix-ldap-sync script we need to create a configuration file describing the various LDAP and Zabbix related config entries.

Config file sections

[ldap]

• type - Select type of ldap server, can be activedirectory or openldap
• uri - URI of the LDAP server, including port
• base - Base Distinguished Name
• binduser - LDAP user which has permissions to perform LDAP search
• bindpass - Password for LDAP user
• groups - LDAP groups to sync with Zabbix (support wildcard - TESTED ONLY with Active Directory, see Command-line arguments)
• media - Name of the LDAP attribute of user object, that will be used to set Send to property of Zabbix user media. This entry is optional, default value is mail.

[ad]

• filtergroup = The ldap filter to get group in ActiveDirectory mode, by default (&(objectClass=group)(name=%s))
• filteruser = The ldap filter to get the users in ActiveDirectory mode, by default (objectClass=user)(objectCategory=Person)
• filterdisabled = The filter to get the disabled user in ActiveDirectory mode, by default (!(userAccountControl:1.2.840.113556.1.4.803:=2))
• filtermemberof = The filter to get memberof in ActiveDirectory mode, by default (memberOf:1.2.840.113556.1.4.1941:=%s)
• groupattribute = The attribute used for membership in a group in ActiveDirectory mode, by default member
• userattribute = The attribute for users in ActiveDirectory mode sAMAccountName

[openldap]

• type = The storage mode for group and users can be posix or groupofnames
• filtergroup = The ldap filter to get group in OpenLDAP mode, by default (&(objectClass=posixGroup)(cn=%s))
• filteruser = The ldap filter to get the users in OpenLDAP mode, by default (&(objectClass=posixAccount)(uid=%s))
• groupattribute = The attribute used for membership in a group in OpenLDAP mode, by default memberUid
• userattribute = The attribute for users in openldap mode, by default uid

[zabbix]

• server - Zabbix URL
• username - Zabbix username. This user must have permissions to add/remove users and groups. Typically, this would be Zabbix Admin account.
• password - Password for Zabbix user
• auth - can be http (for basic auth) or webform (for regular form based login)

[user]

Allows to override various properties for Zabbix users created by script. See User object in Zabbix API documentation for available properties. If section/property doesn't exist, defaults are:

• type = 1 - User type. Possible values: 1 - (default) Zabbix user; 2 - Zabbix admin; 3 - Zabbix super admin.

[media]

Allows to override media type and various properties for Zabbix media for users created by script.

• decription - Description of Zabbix media (Email, Jabber, SMS, etc...). This entry is optional, default value is Email.

You can configure additional properties in this section. See Media object in Zabbix API documentation for available properties. If this section/property doesn't exist, defaults fro additional properties are:

• active = 0 - Whether the media is enabled. Possible values: 0- enabled; 1 - disabled.
• period = 1-7,00:00-24:00 - Time when the notifications can be sent as a time period.
• onlycreate = true - Process media only on newly created users if this is set to true.
• severity = 63 - Decimal value of trigger severities to send notifications about. Each severity value occupies a position of a 6-bit value. Use this table to calculate decimal representation or enumerate the severities separated by a comma:

╔═════════════╦════════╦════╦═══════╦═══════╦═══════════╦══════════════╗
║  Severity   ║Disaster║High║Average║Warning║Information║Not Classified║
╠═════════════╬════════╬════╬═══════╬═══════╬═══════════╬══════════════╣

╠═════════════╬════════╩════╩═══════╩═══════╩═══════════╩══════════════╣
║Decimal value║                     111111 = 63                        ║
║             ║           Linux: printf '%i\n' "$((2#111111))"         ║

Importing LDAP users into Zabbix

Now that we have the above mentioned configuration file created, let's import our groups and users from LDAP to Zabbix.

$ zabbix-ldap-sync -f /path/to/zabbix-ldap.conf

Once the script completes, check your Zabbix Frontend to verify that users are successfully imported.

To sync different LDAP groups with different options, create separate config file for each group and run zabbix-ldap-sync:

$ zabbix-ldap-sync -f /path/to/zabbix-ldap-admins.conf
$ zabbix-ldap-sync -f /path/to/zabbix-ldap-users.conf

You would generally be running the above scripts on regular basis, say each day from cron(8) in order to make sure your Zabbix system is in sync with LDAP.
