Errors installing python-ldap and python-django-auth-ldap

[PeregrineLinux]

Impacted versions

• Distribution: Debian
• Codename: Jessie
• Arch: 64 Bits
• Database: MySQL

Steps to reproduce

• Installed Modoboa
• Tried installing python-ldap django-auth-ldap (following issue Internal Server Error when switching to LDAP authentication #114 -- this in and of itself was not immediately obvious, since the configuration instructions just say "pip install python-ldap django-auth-ldap" without mentioning that it needs to be done in a virtual environment):

su - modoboa
bash
source env/bin/activate
pip install python-ldap django-auth-ldap

Problem was solved by running apt-get install libsasl2-dev python-dev libldap2-dev libssl-dev as root. It would be helpful to update the documentation to reflect all the steps involved.
