Lets say you want to store UserId and all the related lead Id in a map 

 

Map < String, List < Id >> userLeadMap = new Map < String, List < Id >> ();
for (Lead leadObj: [SELECT Id, Owner.Name FROM Lead]) {
    if (userLeadMap.get(leadObj.Owner.Name) == NULL) {
        userLeadMap.put(leadObj.Owner.Name, new List < Id > ());
    }
    userLeadMap.get(leadObj.Owner.Name).add(leadObj.Id);
}

 You can see its pretty simple :)
