Need your guidance in setting up SAMBA 4.2.3 on CentOS7 with proper authentication.

Below are the details of my smb.conf file. 

Problem: incorrect authentication when accessing share from windows machine

a) "worm" share is guest only and can be accessed by any person without authentication
b) "secure_worm" is share which require authentication from the user

when I have only one share(worm or secure_worm) configured in samba, everything works fine, however problem starts when I have both these configuration and user tries to access both share

i) I use \\ which shows me two share named "worm" & "secure_worm", when I click on secure_worm it asks me for user name and password, with correct credentials I can access and work with share, now if I close and open the explorer and try to access these share, I am get into "secure_worm" folder without authentication and I am asked for authentication for the "worm" folder which is incorrect.

If I restart the samba service or restart the workstation service in windows everything works fine for first connection and once I authenticate secure_worm folder, above mentioned problem starts coming up again.
