为了向AAD组添加多个服务主体，我在我的环境中运行了下面的bash脚本，得到了如下的响应：

groupId="groupObjId"
sp_list=("myapp01" "myapp02" "myapp03")

for sp_name in "${sp_list[@]}"
do
    spObjId=$(az ad sp list --display-name "$sp_name" --query '[0].id' --output tsv)

    if [ -n "$spObjId" ]; then
        az ad group member add --group $groupId --member-id $spObjId
        if [ $? -eq 0 ]; then
            echo "Service Principal with Name: $sp_name (Object ID: $spObjId) added to AAD Group successfully."
        else
            echo "Failed to add Service Principal with Name: $sp_name (Object ID: $spObjId) to AAD Group."
        fi
    else
        echo "Service Principal with Name: $sp_name not found."
    fi
done

回复：

当我在Portal中进行相同检查时，服务主体已成功作为成员添加到Azure AD组，如下所示：
