Leaving the old file in place should work. Also replacing it with the new one should work. I guess you did something in between? On Jul 2, 2012 5:27 PM, "Arno Gaboury" wrote:

Dear list,

I messed up my box yesterday when upgrading shadow, and trying to understand and merge /etc/pam.d/login with login.pacnew.

I thought it was worth adding the four lines of login.pacnew to my actual login file. But in this case, I found myself with a box login one user, me, on two Tty, asking for the password twice at the console login prompt, then when X started, all GUI apps were very long to diplay contents, and when I loged off/loged in, I could see I had two last login on Tty messages . So I reverted to my original /etc/pam.d/login. Now everything is OK, but I am wondering if this denial of taling into account the login.pacnew would leave my system unstable.

TY for help and hints, as PAM and shadow are both quite obscure to me when it comes to configure. Below is my actual /ect/pam.d/login . Not sure it is well configured !

#%PAM-1.0

I first tried to replace my login file by the *login.pacnew*. But result was a mess. I then try to add the four lines to my file. Was a mess too, as according to me it created a kind of double login (2 Tty), I don't know why. Now back to the original one.

auth required pam_securetty.so auth requisite pam_nologin.so auth include system-local-login account include system-local-login session include system-local-login The first two ones were already on my system, and I kept away the ones with *system-local-login*. BTW, I couldn't find any reference about

The five lines from *login.pacnew* are these following ones: these 3 lines, even on *red-hat* and *LFS* , which present good documentation about configuring *shadow *and *pam.d* folder.
