[SOLVED FOR NOW]help needed if possible with PAM
« on: April 27, 2013, 07:19:53 AM »
Hi

I lack the skills to know where I am going wrong so lets start at the beginning

I am attempting to compile cups and have done so  but not confident the build is correct.

The trouble is, I am trying to compile a bit of PAM module and I can't see it.

my configure line is
Quote
./configure --prefix=/usr/local --sysconfdir=/usr/local/etc --localstatedir=/var \
--enable-libpaper --disable-libusb --enable-dbus --with-dbusdir=/usr/local/etc/dbus-1 \
--enable-ssl --disable-gnutls --enable-openssl --enable-avahi --enable-dnssd \
--with-cups-user=tc --with-cups-group=staff --with-system-groups=root \
--enable-pam --with-pam-module=pam_unknown.so  --enable-largefile --with-printcap=/usr/local/etc/printcap

The reason why I chose module=pam_unknown.so is because of the contents of a m4 file dated 23/04/2012 called cups-pam.m4 whose contents are
Code: [Select]

dnl "$Id: cups-pam.m4 10424 2012-04-23 17:26:57Z mike $"

Since that file has no date change, I am assuming the module has not changed from anything I do with my configure line.

Feel free to correct my thinking
AFAIK, I can't install to /tmp so have to use a touch /tmp/mark and install into system and use list to find what files to go where
as a result I can see one file being created, which is
/tmp/cups/usr/local/etc/pam.d
Quote
auth   required   pam_unknown.so nodelay
account   required   pam_unknown.so

SIDETRACK in current cups that config file uses the module pam_unix.so and that so file exists in Linux-Pam under
/usr/local/lib/security

but after install , if I am supposed to have that other module name, it does not exist in that pathway nor in the list output.

As you can tell, PAM is not my strength. In case my eyesight is playing up lets try
Code: [Select]
sudo find / -name pam_unknown.so but it produces no hits

thanks for reading

Questions
1)
Is this some kind of trick? and should I try the other modules I can see in the m4 they are: pam_unix.so, pam_unix2.so

2)  Or
Am I supposed to modify those pathways I can see in the m4 eg /lib/security?

ok I have solved by cheating and using a config file from another distro

I have not worked out how to re-config the m4 file but who cares

I can now login to cups 1.6.2 now to test dependencies for an USB direct cable TC to epson TX-100

yep qpdf

woo hoo
contents of page log.............localhost:631/admin/log/page_log?
Code: [Select]
EPSON_Stylus_TX100 tc 5 [28/Apr/2013:18:13:22 +0000] 1 1 - localhost Leafpad job #2 - -

it printed

 ;D ;D

lots more testing to go but we are now closer to the end
