ubuntu 16.04 python-ldap and python-ldappol conflict

[Matthew J Black]

When setting up ldap in keystone it will install the ldap packages needed. Installing python-ldap uninstalls python-ldappool. Installing python-ldappool will uninstall python-ldap. Once python-ldappool is uninstalled, keystone will throw exceptions.

The recommendation is to install only python-ldappool. A portion of the apt output is pasted below showing the python-ldap package being uninstalled.

$ sudo apt-get install python-ldappool

The following NEW packages will be installed:

After taking a look at CentOS image, it's the same there the only difference is that YUM resolves the issue each run.

    fix ldap packages for keystone backend

    When puppet runs it will try to install python-ldap and
    python-ldappool. Each run will install one or the other
    due to the other package settings telling the package
    manager to uninstall it.
