The SSSD needs a config_from_fd() variant of the config_from_file() call so that we can preopen a config file and perform some verification on it before parsing it. The config_from_fd() call is used to avoid race conditions between testing the file and reading it in.
Note: the *_from_fd() functions still require the config file name for internal information. This does not imply that it is used to open the file.
I think it is better not to require a file name, and, internally, just use something like "dummy" or a random string like the process pid etc..
This way there is no risk that someone may accidentally change the code later to re-open the file or something like that, if that is done it will immediately break when it tries to open "dummy" (hopefully :-)
Simo.
