freebsd nis and solaris

[rchitecture]

freebsd 6.1   solaris9

questions on the freebsd side:( internal machine running no firewall)   
- soalris 9 is the yp server, and two ypslaves are also on solaris 9

built a freebsd 6.1 and i am running into some problems

*******************************************************

when i initiate ypcat command, all results return correctly

i have standard nis map, like auto_volume/auto_home/packages......pretty 
standard

all i need from this yp services is to be able to

ie cd /home/xxxx  and /volume/yyyy, and its not showing up, it just 
hang, control c to get out

also i've mande a mount point on the freebsd machine, ie 
/raid7.....already setup in the yp auto_volume, but from
a solaris machine, if I go ...cd /volume/raid7, i got permission denied, 
but its completely open!

does anyone have some howto?????
