Dear Experts, 
Please help
I am having problem with mount via NIS
Is there anything wrong with this
All IP and name are fake

On server :
bash-3.2# showmount -e 1.1.1.1
export list for 1.1.1.1
/vol/netapp1/vol1/X build
/vol/netapp1/vol1/Y  build

Error on server
mount 1.1.1.1:/vol/netapp1/vol1/X  /testnetapp
nfs mount: 1.1.1.1:/vol/netapp1/vol1/X : Permission denied

On filer

#ypmatch -k build netgroup
build (1.1.1.2,-,-) (1.1.1.3,-,-) 

#ypcat -k netgroup
build (1.1.1.2,-,-) (1.1.1.3,-,-) 

#exportfs
/vol/netapp1/vol1/X   -sec=sys,rw=@build
/vol/netapp1/vol1/Y    -sec=sys,rw=@build
