24 This function requires sys_getgrouplist - which is only
25 available in smbd due to it's use of become_root() in a
30 return a full list of groups for a user
32 returns the number of groups the user is a member of. The return will include the
35 remember to free the resulting gid_t array
37 NOTE! uses become_root() to gain correct priviages on systems
38 that lack a native getgroups() call (uses initgroups and getgroups)
40 int getgroups_user(const char *user, gid_t **groups)
45 pwd = getpwnam_alloc(user);
48 max_grp = groups_max();
49 (*groups) = (gid_t *)malloc(sizeof(gid_t) * max_grp);
56 ngrp = sys_getgrouplist(user, pwd->pw_gid, *groups, &max_grp);
