[Samba] initialise groups winbind making samba useless

[Edward Mann]

I have posted with this error/bug before, so now i am back at it again.
I am having a problem with samba, winbindd and groups. If a users is in
a large number of groups i get the following error when they try to
connect to the samba server

Oct 31 18:00:44 localhost smbd[11086]: [2002/10/31 18:00:44, 0]
smbd/sec_ctx.c:initialise_groups(244)

They cannot connect to any of the shares now.

How do i fix this?

I am using samba-2.2.6
RedHat 7.3
Kernel 2.4.19
libgcc-3.0.1-3

What other info do you need to help fix this problem. Even if someone
would write me back and tell me that i'm totally screwed, that would be
better than nothing.

I will say that this is the first time that i have posted a question to
the net and no one could respond to it. Is this something that only i am
having problems with?
