I'm used to configuring Ipsilon server with

ipsilon-server-install --pam yes

However, with 0.3.0, that started to fail with

ipsilon-server-install: error: unrecognized arguments: --pam yes

I had to install python-pam and ipsilon-authpam -- this should be noted at https://fedorahosted.org/ipsilon/.

However, even with that, I got

  File "/usr/lib/python2.7/site-packages/ipsilon/helpers/ipa.py", line 171, in configure_server
    if opts['ipa'] != 'no':
KeyError: 'krb'

and I had to also install ipsilon-authkrb to get rid of that error.

Maybe some has_key is needed?

In general, minimal installations / configurations should be possible without installing all the plugins, otherwise the plugins are not that useful. And needed plugin packages for various options should be spelled out in the documentation.
