This group and user was created automaticaly. I tried add user rslsync to group root, but without result. Also I can not change permission for sync folder, it's important
[root@server ~]# cat /etc/passwd | grep rsl
rslsync:x:499:498::/home/rslsync:/sbin/nologin
[root@server ~]# cat /etc/group | grep rsl
root:x:0:rslsync
rslsync:x:498:
