Enabling/Disabling user via set_user_attribute does not behave as expected

[Sebaristoteles]

Hi,

I am using pyocclient to administer users and groups. Creation, adding, and removing works well.
For some use case, I want to disable a user. The option that I found was via 'set_user_attribute'. This works for each changing the name of the user.
When I use get_user('name'), I get either the key-value-pair "'enabled': None" or "'enabled': '1'". In each case, I cannot change to the other option with "set_user_attribute('name', key='enabled', value=None)" or "oc.set_user_attribute('name', key='enabled', value='1')".

If you wonder why you might not have this key-value-pair, I am using the pyoclient for administering a Nextcloud. This works well with the provided functions. I think my question is still valid because the switch between 'None' and some value like '1' might still be a use case for owncloud user attributes.

Thanks for consideration!
