Getent problem in samba 2.2

[ncc22, Gecis (CAP, GECIS)]

Hi!
I am using samba 2.2.2 in NT Domain as a member server. I am able to do wbinfo -u and wbinfo -g. Both the commands are working properly but I am not able to get domain users
password and group information through 

getent passwd and getent group 


Please help me how to rectify this problem.
