XDMCP - Never see Chooser or Login

[Greg Pratt <gpratt valinux com>]

Hello,
I have configured gdm to support XDMCP, but I never see the login or
chooser when I execute X -query 10.10.10.9 (my XDMCP host).

[xdmcp]
Enable=1
HonorIndirect=0
MaxPending=4
MaxPendingIndirect=4
MaxSessions=16
MaxWait=30
MaxWaitIndirect=30
Port=177

Here is what I see in my log on the XDMCP host:

Jan 18 18:36:56 vadaltst09 gdm[554]: gdm_xdmcp_manage: Got MANAGE from
10.10.10.1
Jan 18 18:37:01 vadaltst09 gdm[554]: gdm_xdmcp_manage: Got Display=0,
SessionID=979864442 from 10.10.10.1
Jan 18 18:37:01 vadaltst09 gdm[554]: gdm_xdmcp_handle_manage: Failed to
look up session id 979864442
Jan 18 18:37:01 vadaltst09 gdm[554]: gdm_xdmcp_send_refuse: Sending
REFUSE to 979864442
Jan 18 18:37:01 vadaltst09 gdm[554]: gdm_xdmcp_decode: Could not create
XDMCP buffer!  

Any tips would be appreciated.
