Full Discussion: Problem with files/dirs deletion
Operating Systems Linux Debian Problem with files/dirs deletion Post 302772632 by pentago on Tuesday 26th of February 2013 09:11:46 AM

Well yeah, i was told that apache/php runs with my user as a security precaution.

Maybe i din't explained it very well, im not very skilled..
Anyway, from what i understood, such behavior is common practice on shell accounts where multi user environment is in place.

I can't switch to myusername-www, it gives me authentication failure

Code:
% su pentago-www
Password:
su: Authentication failure

Could you please elabore on how do i add myself to group with proper permissions?

Thanks!

pam_sm_authenticate

PAM_SM_AUTHENTICATE(3)						 Linux-PAM Manual					    PAM_SM_AUTHENTICATE(3)

NAME

       pam_sm_authenticate - PAM service function for user authentication

SYNOPSIS

       #define PAM_SM_AUTH

       #include <security/pam_modules.h>

       PAM_EXTERN int pam_sm_authenticate(pam_handle_t *pamh, int flags, int argc, const char **argv);

DESCRIPTION

       The pam_sm_authenticate function is the service module's implementation of the pam_authenticate(3) interface.

       This function performs the task of authenticating the user.

       Valid flags, which may be logically OR'd with PAM_SILENT, are:

       PAM_SILENT
	   Do not emit any messages.

       PAM_DISALLOW_NULL_AUTHTOK
	   Return PAM_AUTH_ERR if the database of authentication tokens for this authentication mechanism has a NULL entry for the user. Without
	   this flag, such a NULL token will lead to a success without the user being prompted.

RETURN VALUES

       PAM_AUTH_ERR
	   Authentication failure.

       PAM_CRED_INSUFFICIENT
	   For some reason the application does not have sufficient credentials to authenticate the user.

       PAM_AUTHINFO_UNAVAIL
	   The modules were not able to access the authentication information. This might be due to a network or hardware failure etc.

       PAM_SUCCESS
	   The authentication token was successfully updated.

       PAM_USER_UNKNOWN
	   The supplied username is not known to the authentication service.

       PAM_MAXTRIES
	   One or more of the authentication modules has reached its limit of tries authenticating the user. Do not try again.
