While I was debugging why my FreeRADIUS build (3.0.x) did not work with the direct winbind calls on Debian stable, I noticed that the configure script does some checks for membership.h: checking for membership.h... no checking for membership.h in /usr/local/include/... no checking for membership.h in /opt/include/... no Outside of the configure-script, there is no reference to this file in the rlm_mschap folder. (There is one in rlm_opendirectory though). Debian Stable does not appear to have any package with a file membership.h <https://packages.debian.org/search?searchon=contents&keywords=membership.h&mode=path&suite=stable&arch=any>. Is there any reason this file is being checked in configure, or is it just a leftover of copy-pasto that is irrelevant now? -- Herwin Weststrate
