Force GUAM to exclusively listen on IPv4
I was recently trying to completely disable IPv6 on a kolab-enabled host. In order to not have services complaining about not having access to an IPv6 address, I tried to turn them off one by one before finally disabling IPv6 system-wide.
For most of the services I could easily find configuration options in order to achieve that, but when I came to GUAM, I could not find a way to do the same. Did I miss something in the documentation?
A note to the developers: GUAM seems to be constantly crashing when only IPv4 is available.
I don't know erlang, but it looks to me as it's hardcoded here https://git.kolab.org/diffusion/G/browse/master/apps/kolab_guam/src/kolab_guam_listener.erl;417fec0be3df14c157bd10915892ba8f90c224e6$78
