Hi, I have recently setup CENTOS ver.4.4 as our mail server and I have installed Squirrelmail as our Mail User Agent. Everything seems to be working fine but I encountered problems in one of the plugins of Squirrelmail which is the Change Password plugins that changes the password in the shadow file. The change password function doesn't seems to work because Squirrelmail replies an error message that does not allow the change password function to change the password of the users. My first guess is because of the file security setting and I can't seems to go around this. One thing I notice though is that when the file is inside the /var/www/html/ directory, the php scripts that I have tried to edit a file seems to work but if the file is outside this directory just in the case of the shadow file which is located at /etc/ directory it doesn't seems to work or it does not allow the file to be modified. Can you please help with this? I would really appreciated your help.
