Runtime

• custodia >= 0.3.1

virtualenv requirements

custodia.ipa depends on several binary extensions and shared libraries for e.g. python-cryptography, python-gssapi, python-ldap, and python-nss. For installation in a virtual environment, a C compiler and several development packages are required.

$ venv/bin/pip install --upgrade custodia.ipa

Fedora

$ sudo dnf install python2 python-pip python-virtualenv python-devel \
    gcc redhat-rpm-config krb5-workstation krb5-devel libffi-devel \
