about error: id: cannot find name for group ID while switching users

[esolve]

Hi, when I switch between users, I always see error:
" cannot find name for group ID"
what is wrong with this?
thanks

[esolve at goeland esolve]$ su su4089
Password: 
[root at goeland esolve]# su esolve
id: cannot find name for group ID 1150
[esolve at goeland esolve]$

[esolve at goeland esolve]$ id
uid=40078(esolve) gid=1150 groups=1150

Have you looked in /etc/group for this group id?
