python – ldap3 lib: How to add multiple values to attribute

I want to add more than one email adress to a user in ldap. Therefore is an attribut called mailLocalAdress that looks like this when I search/find a specific user with ldapsearch:

mailLocalAddress: [email protected]
mailLocalAddress: [email protected]
mailLocalAddress: [email protected]

I’m using python 3, the ldap3 lib and this is how I define the value for the mailLocalAdress attribute

ldap_values['mailLocalAddress'] = [user.email_first, user.email_second, user.email_third]

and this is the add command

ldap_con.add(dn, object_class, ldap_values)

and I got this as result when doing ldapsearch

Any ideas how to get the listing above?

Answer

I’m not able to reproduce the behavior you’ve reported. If I start with this in my ldap directory:

dn: dc=example,dc=com
objectclass: dcObject
objectclass: organization
o: example
dc: example

dn: ou=people,dc=example,dc=com
objectclass: organizationalunit
ou: people

And then run the following Python code:

>>> from ldap3 import Server, Connection, ALL
>>> server=Server('localhost')
>>> conn = Connection(server, user='cn=manager,dc=example,dc=com', password='secret')
>>> conn.bind()
True
>>> dn='uid=alice,ou=people,dc=example,dc=com'
>>> object_class=['person', 'organizationalperson', 'inetorgperson', 'inetlocalmailrecipient']
>>> ldap_values={'sn': 'example', 'cn': 'alice example', 'mailLocalAddress': ['[email protected]', '[email protected]']}
>>> conn.add(dn, object_class, ldap_values)
True
>>>

An ldapsearch returns:

/etc/openldap # ldapsearch ... -b dc=example,dc=com uid=alice
# alice, people, example.com
dn: uid=alice,ou=people,dc=example,dc=com
sn: example
cn: alice example
mailLocalAddress: [email protected]
mailLocalAddress: [email protected]
objectClass: person
objectClass: organizationalPerson
objectClass: inetOrgPerson
objectClass: inetLocalMailRecipient
uid: alice

Which seems to be exactly what you want.
