Bug 101672 – proftpd links against pam if it's installed, even when emerge with USE="-pam"

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description David Morgan 2005-08-07 12:59:26 UTC]

If proftpd is emerged with -pam in USE but pam is installed, then proftpd links
against pam, and needs to be rebuilt if pam is then unmerged.

[ebuild   R   ] net-ftp/proftpd-1.2.10-r7  -authfile +hardened -ipv6 -ldap
-mysql +ncurses -noauthunix -pam -postgres (-selinux) -sendfile -shaper
-softquota +ssl +tcpd -xinetd 0 kB

 * Starting proftpd ...
/usr/sbin/proftpd: error while loading shared libraries: libpam.so.0: cannot
open shared object file: No such file or directory

Patch to prevent PAM from being enabled despite -pam

[Comment 3 David Morgan 2005-08-07 13:48:11 UTC]

The same thing happens (though --disable-pam is being passed to configure)

This is from configure btw:

checking security/pam_appl.h usability... yes
checking security/pam_appl.h presence... yes
checking for security/pam_appl.h... yes
checking pam/pam_appl.h usability... no
checking pam/pam_appl.h presence... no
checking for pam/pam_appl.h... no
checking for pam_start in -lpam... yes

Pam patch -- part two!

[Comment 6 David Morgan 2005-08-07 14:28:50 UTC]

Same thing happens (though --without-pam gets used)

This sounds like proftpd just not playing by the rules. According to their
README.modules, mod_pam is included no matter what if it is found.
However, after playing around, I've found a method to stop configure from
including it. See attachment.

Last try!

[Comment 9 Chris Slycord 2005-08-08 21:37:13 UTC]

I've tried every combination of those patches I could and at some point it fails
due to not finding pam.

Looks like it needs --enable-auth-pam=no passed to configure. There's a hopefully fixed ebuild in Bug 111668, give it a try.

# ./configure &> config.log; grep pam config.log

checking security/pam_appl.h usability... yes
checking security/pam_appl.h presence... yes
checking for security/pam_appl.h... yes
checking pam/pam_appl.h usability... no
checking pam/pam_appl.h presence... no
checking for pam/pam_appl.h... no
checking for pam_start in -lpam... yes

# ./configure --enable-auth-pam=no
#

OK, this works for me (didn't get into 1.3.0-r1 unfortunately)

<snip>
use pam && modules="${modules}:mod_auth_pam"
# pam needs to be explicitely disabled - see README.PAM
use pam || myconf="${myconf} --enable-auth-pam=no"
</snip>

Fixed in net-ftp/proftpd-1.3.0-r2. Thanks for the fix!
Best regards, CHTEKK.
