Hi I have webmin 1.510-2 installed on ubuntu server 10.4
I want to create share a folder placed on the Ubuntu server in Windows.
under Server/Samba i have configured every thing and i can see the shared folder in windows file manager. but i cannot create folders or add files to this folder. it says access denied. i have given all the right configurations based on webmin samaba configuration and i login with an account which has administrative permission on Ubuntu server.
can any one tell me what is not right here? this is very strange.
