What is the best LDAP structure when you want users being part of multiple groups?

I’m relatively new to LDAP. I have open-ldap LDAP v3 installed. I’ve seen things like this:

dn: cn=Giuseppe LoBiondo, ou=people, dc=yourorg, dc=com
cn: Giuseppe Lo Biondo
sn: Lo Biondo
objectclass: top
objectclass: person
objectclass: posixAccount
objectclass: shadowAccount
uid:giuseppe
userpassword:{crypt}$1$ss2ii(0$gbs*do&@=)eksd
uidnumber:104
gidnumber:100
gecos:Giuseppe Lo Biondo
loginShell:/bin/zsh
homeDirectory: /home/giuseppe
shadowLastChange:10877
shadowMin: 0
shadowMax: 999999
shadowWarning: 7
shadowInactive: -1
shadowExpire: -1
shadowFlag: 0

dn: cn=mygroup, ou=groups, dc=yourorg, dc=com
objectclass: top
objectclass: posixGroup
cn: mygroup
gidnumber: 100
memberuid: giuseppe
memberuid: anotheruser

I’ve also seen setups where you don’t have memberuid, but rather just member. Any suggestions or resources?
