It calls the following code:
static void set_user(const char *user)
struct passwd *ent;
// don't bother if we aren't superuser
if(!(ent = getpwnam(user))) <-- fails here
if (setgid(ent->pw_gid) == -1)
if (setuid(ent->pw_uid) == -1)
I have now idea why getpwnam fails with 'success'.
Magnus; Are you sure that you have a user named 'mysql' ?
