Можете ли вы проверить группу пользователей через $ remote_user?

location ~ ^/dav/(.*)$ {
    alias /home/$remote_user/$1;
    auth_pam "Restricted";
    auth_pam_service_name "nginx";
    dav_methods PUT DELETE MKCOL COPY MOVE;
    dav_access group:rw all:r;
    create_full_put_path on;
}

location ~ ^/home/(.*)$ {
    alias /home/$1;
    #check the group of the $remote_user;
}

curl -T test.txt 'http: // gert: passwd@127.0.0.1/dav/'
