[Openswan Users] ipsec.secrets questions?

[hallian hallian]

Hi all -

I have been surfing around but wanted to confirm?  If I have three (3) 
site-2-site connections can I use

# cat /etc/ipsec.secrets
site1_ip site2_ip : PSK "thekey1"
site1_ip site3_ip : PSK "thekey2"
site1_ip site4_ip : PSK "thekey3"

Is this the right method/syntax for ipsec.secrets for mulitple connections 
with different pre-shared keys?

Thanks
Hallian
