StrongSwan – How to Link IPsec Clients with Different Connections

I use strongswan ipsec as VPN gateway for mobile devices (Android). In StrongSwan config I've setup 2 connections (two different subnets 10.10.10.0/24, 10.10.20.0/24 with different routing policies) for 2 different groups of users.

And I don't understand (and can't find in manuals and forums) how to link user with connection. Where and how to setup a strict user>connection relation ?

Thank you!

My ipsec config:

cat /etc/ipsec.conf

config setup
    charondebug="ike 1, knl 1, cfg 0"
    uniqueids=no
conn any2ex
    auto=add
    compress=yes
    type=tunnel
    keyexchange=ikev2
    fragmentation=yes
    forceencaps=yes
    dpdaction=clear
    dpddelay=300s
    rekey=no
    left=%any
    leftid=*.*.233.132 #I've masked server IP for this post. Certificate was issued for the ip address.
    left=*.*.233.132  
    leftcert=server-cert.pem
    leftsendcert=always
