    Maybe related to: https://stackoverflow.com/questions/54648246/invalid-syntax-in-more-itertools-when-running-pytest


    I can confirm that requiring a more-itertools dependency that is less than 6.0.0 is required to fix this issue when using Python 2. There is a python3 branch to LdapCherry, and I don't know if the migration is going to be soon, or if the maintainer plans to maintain two versions.

    I also obtained the same error while starting ldapcherry

    [root@ldapcherry scripts]# ldapcherryd -c /etc/ldapcherry/ldapcherry.ini -D

    The foll. workaround seems to resolve this issue: (CentOS 7.2/Python 2.7.5 and ldapcherry 1.1.1)

    $ pip install 'more-itertools<=5.0.0'

    This is the correct fix. This issue should be marked as closed.
