AIX and winbind users, works fine all except for:""I have no name!"

I want winbind auth in AIX. Samba works fine: wbinfo -g cert publishers dnsadmins domain guests group policy creator owners domain computers allowed rodc password replication group domain controllers domain users ras and ias servers denied rodc password replication group read-only domain controllers domain admins enterprise read-only domain controllers schema admins enterprise admins dnsupdateproxy Also wbinfo -i user works wbinfo -i myuser myuser:*:10003:10000::/home/myuser:/opt/freeware/bin/bash I have configured the auth in this way i modify the file /etc/security/users in this way system = "compat or WINBIND" I have modified also /usr/lib/security/methods.cfg WINBIND: program = /opt/freeware/lib/WINBIND.so program_64 = /opt/freeware/lib/WINBIND.so NIS: program = /usr/lib/security/NIS program_64 = /usr/lib/security/NIS_64 DCE: program = /usr/lib/security/DCE All commands works(ssh,lsuser,id,etc) but in the shell prompt I get for non winbind user nonwinbinduser@aix:~$ for winbind user I have no name!@aix:~$ What I miss?
