samba - Jan 2006 - "PANIC: failed to set gid" on mipsel

I just compiled Samba 3.0.21a for Linux/mipsel/uclibc.

When I want to start smbd, it fails:

[2006/01/19 12:29:09, 0] lib/util_sec.c:assert_gid(113)
   Failed to set gid privileges to (-1,65534) now set to (0,0) uid=(0,0)
[2006/01/19 12:29:09, 0] lib/util.c:smb_panic2(1554)
   PANIC: failed to set gid


The only way to start smbd is to put this into smb.conf:

guest account = root

But I'm not sure if it's a great idea.


smbd doesn't start with guest account set to nobody.

I have that user in /etc/passwd and /etc/group though:

root@OpenWrt# cat /etc/passwd
root:xxxxxxxxxxxxxxxxxxx:0:0:root:/root:/bin/ash
nobody:*:65534:65534:nobody:/var:/bin/false

root@OpenWrt:/tmp/log/samba# cat /etc/group
root:x:0:
nogroup:x:65534:


I've checked the archives, there were similar errors, but mostly when 
user wanted to change the password on Samba 2.x.

Any ideas why can't I start smbd when "guest account = nobody"?

I edited include/config.h, and added "#define USE_SETRESUID 1":

/* Whether setresuid() is available */
/* #undef USE_SETRESUID */
#define USE_SETRESUID 1

Compiled, and now smbd starts correctly.
