[Samba] GID-to-SID mapping fails

[Matt Seitz]

Name-to-SID works:
[root at paris mpmCx]# wbinfo -n QA4\\DnsUpdateProxy
S-1-5-21-3152226350-2923503207-3337354198-1105 Domain Group (2)

SID-to-Name works
[root at paris mpmCx]# wbinfo -s S-1-5-21-3152226350-2923503207-3337354198-1105
QA4\DnsUpdateProxy 2

SID-to-GID works:
[root at paris mpmCx]# wbinfo -Y S-1-5-21-3152226350-2923503207-3337354198-1105
10010

GID-to-SID fails:
[root at paris mpmCx]# wbinfo -G 10010
Could not convert gid 10010 to sid

Any suggestions?
