Thank you for your work on this patch.

It looks OK apart from a few syntax changes required. But I'm not comfortable merging it because this is a gitlab EE feature that I can't test. I'm not sure how I could automate testing and make sure the code works.

Oh, I totally forgot this annoying detail :/
I believe the enterprise edition is actually installable without a license (it's user based), so I could ask the Gitlab guys if they could issue a sort of "for automated testing purposes" blanket license. Than you could test against EE. Would you be OK with this? (assuming it's possible...)

It's worth a try. I'd be happy to add EE features to the lib. Thanks!

Just added a commit that changes the testing to use a fork of your test-python-gitlab docker image using gitlab EE, but I keep getting timeouts. Strangely enough my local docker image seems to work...
Also, the timeouts don't seem to signal a build-failure since the whole functional testing is done inside after_success. Was this intentional?

I used after_success to avoid running the functional tests multiple times. Maybe this is not such a good idea. I'll try to find a better way to do it as soon as I can but this might take time. Feel free to change the travis config to test possible updates.

Thank you for your work on this!

I have this working (create/delete) on 1.4.0:

from gitlab.base import RESTObject, RESTManager
from gitlab.mixins import CreateMixin, DeleteMixin
import gitlab.v4.objects

class GroupLdapGroupLink(RESTObject):
    pass


class GroupLdapGroupLinkManager(CreateMixin, DeleteMixin, RESTManager):
    _path = '/groups/%(group_id)s/ldap_group_links'
    _obj_cls = GroupLdapGroupLink
    _from_parent_attrs = {'group_id': 'id'}
    _create_attrs = (('cn', 'group_access', 'provider'), tuple())

gitlab.v4.objects.GroupLdapGroupLinkManager = GroupLdapGroupLinkManager

gitlab.v4.objects.Group._managers = tuple(
    gitlab.v4.objects.Group._managers + (('ldapgrouplinks', 'GroupLdapGroupLinkManager'), )
)

The LDAP group link API endpoint being quite different from the other endpoints I implemented support for this feature as Group methods instead of new classes. See commit d6a61af.
