Error: modification must be an Attribute on groupOfNames member modify ldapjs

Question

I have a code that should add an user to a groupOfNames in ldapjs

  function addUserToGroup(userDN, groupName, callback) {
    const groupDN = `cn=${groupName},ou=groups,dc=XXX`;
    console.log(userDN);
    console.log(groupDN);
    const change = new ldap.Change({
      operation: 'add',
      modification: {
        member: [userDN],
      },
    });
  
    client.modify(groupDN, change, (err) => {
      if (err) {
        console.error('Error adding user to group:', err);
      }
      callback(err, groupDN);
    });
  }

  addUserToGroup('uid=3d4dfc3d-7493-4a1d-9659-f1799a48a927,ou=people,dc=XXX', 'everybody', (err) => {
    if (err) {
      console.error('Error assigning user to group:', err);
    }
  });

but it throws this error

uid=3d4dfc3d-7493-4a1d-9659-f1799a48a927,ou=people,dc=XXX
cn=everybody,ou=groups,dc=XXX

[nodemon] app crashed - waiting for file changes before starting...

I change the code with some example online but could not find the working one. Any help?

Answer 1

I got the same error, however, I got the solution,

const userPasswordAttribute = new ldap.Attribute({
  type: 'member',
  values: userDN
});

const change = new ldap.Change({
  operation: 'add',
  modification: userPasswordAttribute
});

You may refer to the page for detail.

I am using ldapjs version 3.0.5
