Samba share write permisions working for windows but not working for linux

Hello,

I made some SMB shares on OMV that work perfectly on different Windows systems.

I can access to these shares without any problem from my Debian 12 system but in read mode only. I can´t create or delete file or directory, a permission denied appears every time.

This is my fstab entry :

//192.168.1.10/Documents /media/share/Documents cifs _netdev,users,auto,guest,rw 0 0

Can someone help me on that?

Thanks
