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.
