bind Lion to snow lepard server but get network profiles

we have a open directory that is currenty running on a mac osx snow lepard server. we have binded some lion macbook pros but when we log off it does not display the list of users on the network it just shows the local accounts and other. If we go in though other we can log into the netowrk profile but we would prefer to get a list instead of manual typing it in all the time. we have checked that the list of names is checked in the users and groups. any advice?? can it be done??
