Hi,
are there any SSSD users who actively use a configuration with: id_provider=local ? If so, what is your use-case?
We're considering deprecating and eventually removing this provider upstream. The replacemant for id_provider=local would be id_provider=files: https://fedorahosted.org/sssd/wiki/DesignDocs/FilesProvider which is already under review and later extension of the SSSD's D-Bus interface to allow manipulating custom user attributes.
My current plan for deprecating the local provider is to only build the provider and the tools around it if a configure-time flag is provided. This flag would be disabled by default. Then, if noone complains, eventually just remove the code.
