Is it possible to authenticate with savannah, e.g. with ldap?

[Friedrich Beckmann]

Hi everybody,

I am member of the https://savannah.gnu.org/projects/pspp project. I am 
currently investigating how to run a continuous integration server for building 
the pspp software. One part of that is to allow the pspp project members to 
modify and control the build server, e.g. to trigger a new build. 

Is it possible to authenticate users via some savannah infrastructure? Is there 
for example an ldap server which I could contact from the build server? 
Currently I am looking at buildbot. They have something to authenticate against 
github or gitlab or plain user/password. I would prefer to use the 
user/password from savannah.

Regards

Friedrich
