winbind: provide passwd struct for group sid with ID_TYPE_BOTH mapping (again)
https://git.samba.org/?p=samba.git;a=commitdiff;h=394622ef8c916cf361f8596dba4664dc8d6bfc9e originally introduced the above feature.
This functionality was undone as part of "winbind: Restructure get_pwsid" https://git.samba.org/?p=samba.git;a=commitdiff;h=bce19a6efe11980933531f0349c8f5212419366a I think that this semantic change was accidential.
This patch undoes the semantic change and re-establishes the functionality.
