389 Directory Server’s primary use is storing users and groups. In this we will show you how to create basic users and groups.

You may find tools like ldapvi and Apache Directory Studio useful for this task.

LDIF


LDAP modifications are performed through the LDAP Data Interchange Format. This describes object additions, deletion, or modification.

Addition takes the form:

dn: <fqdn to add>
changetype: add
objectclass: ...
attributes: ...

Delete takes the form:

dn: <fqdn to delete>
changetype: delete

Modifications takes the form:

dn: <fqdn to alter>
changetype: modify
<action>: attribute
attribute: new value

Action must be one of “add” to add new attribute values, “replace” to change an attribute and “delete” to remove an attribute value.

NOTE: Always take backups before performing changes on production systems

These files are then applied to the server with the “ldapmodify” command. For example:

ldapmodify -f "example.ldif" -D 'bind dn' -H ldap://<hostname>

Creating groups


To create a posix group you can use the following template:

dn: cn=GROUPNAME,ou=Groups,dc=example,dc=com
changetype: add
objectClass: top
objectClass: posixGroup
objectClass: groupOfUniqueNames
gidNumber: 12345
cn: GROUPNAME
# uniqueMember: <DN of member>

Creating users


To create a posix user you can use the following template:

dn: uid=USERNAME,ou=People,dc=example,dc=com
changetype: add
uid: USERNAME
objectClass: top
objectClass: account
objectClass: posixaccount
objectClass: inetOrgPerson
objectClass: person
objectClass: inetUser
objectClass: organizationalPerson
uidNumber: 1001
gidNumber: 1001
sn: surname
homeDirectory: /home/username
cn: common name

If you wish to set a password on the account:

userPassword: <cleartext password>

The server will hash the password securely for you.
