14DESCRIPTION
15===========
16
17This module provides a Perl interface to the PAM library.
18
19Home site: <http://nik.pelov.name/Authen-PAM/>
20
21After installing the module you can read a small faq with
22examples by typing 'perldoc Authen::PAM::FAQ'.

25PREREQUISITES
26=============
27
28Before you can build Authen::PAM you need to have the following
29things installed on your system:
30
31 * Perl, at least version 5.003_23
32 * This module is known to work with the following or newer
33 implementations of the PAM library:
34 - Linux-PAM <http://www.kernel.org/pub/linux/libs/pam/>
35 - Solaris 2.6
36 - FreeBSD 3.1
37 - OpenPAM <http://openpam.sourceforge.net/>
38 - HP-UX 11.0
39 - Darwin 6.0 and Mac OS X 10.2

42BUILDING AND INSTALLING THE MODULE
43==================================
44
45Assuming you have met all the prerequisites, you can built the module
46using the standard sequence of commands:
47
48 perl Makefile.PL
49 make
50 make test
51 make install
52
53By default the module is build using the compiler and options used to build
54the perl executable itself. If you want to change the C compiler then set
55the CC environment variable, for example like this:
56
57 CC=gcc perl Makefile.PL
58
59However, besides changing the compiler, it is still not possible to change
60any other options (for example CFLAGS). If you want to do this then you
61should edit by hand the generated Makefile.
62
63If you have any problems in building and installing the module then
64you should first check on the home page of the Authen::PAM module for
65the latest development version (if any) which could possibly fix your
66problems. If none is available or the problems remain then you can
67write me a mail which includes the following information:
68 * the version of your unix - `uname -a'
69 * the configuration of the perl - `perl -V'
70 * if you are on linux:
71 - the name and version of the distribution you are using
72 - the version of the pam - `ls /lib/libpam.so*' or `ls /usr/lib/libpam.so*'
73 * the description of the "login" service from your pam configuration -
74 usually found in `/etc/pam.conf' file or in the file `/etc/pam.d/login'
75 * the output of the `perl Makefile.PL', `make' and `make test'
76 * any relevant messages produced by the syslogd daemon -
77 usually found in `/var/log/messages'
78 * if the problem is in a perl script which uses the Authen::PAM module then
79 the source of this script (even if it is a slight modification of some
80 of the source code provided with this module)

83KNOWN PROBLEMS
84==============
85
86 Missing PAM header files
87 ------------------------
88
89 I know that this is trivial, but some people actually report this.
90 If you get an error like
91
92 PAM.xs:11: security/pam_appl.h: No such file or directory
93
94 this means that either you don't have the PAM library installed on
95 your system or at least the PAM header files are missing. If your
96 distribution provides the PAM library as packages then you should
97 check that you also have installed the pam-dev or pam-devel package.
98
99
100 FreeBSD 4.x
101 -----------
102 Several people have reported the following error during 'make test':
103 not ok 10 (28 - Module is unknown)
104 I've tracked down the problem to the dynamic loader of FreeBSD not
105 exporting some symbols in dlopen()'d modules. I've submitted a bug
106 report - http://www.freebsd.org/cgi/query-pr.cgi?pr=25059
107 It seems that this bug has been fixed already and starting
108 from the next release of FreeBSD (probably 4.6) the module should
109 work again.
110
111
112 Solaris 2.8
113 -----------
114 Some users are reporting the following error during 'make test':
115 Segmentation Fault - core dumped
116 make: *** [test_dynamic] Error 139
117 The problem seems to be related with the use of Kerberos
118 authentication (pam_krb5 or pam_krb54). At this moment I don't have
119 any explanation for it.
120
121
122 Login Restrictions
123 ------------------
124 Most of the current configurations of the 'login' service include a
125 module 'pam_securetty' or 'pam_access' which restrict the login of
126 some users (especially root) depending on the tty or the host name
127 they are logging from. The configuration files of these two modules
128 are /etc/securetty and /etc/security/access.conf respectively.
129 So, if you are running 'make test' and get an error
130 '(Authentication failure)' on test 10 then this might be due to
131 login restrictions of PAM.
132
133
134 Deprecated
135 ----------
136
137 The following problems occured on old versions of libraries and OSes
138 and are not included in the README file anymore. If you experience them,
139 check the README file in older versions of the PAM library (0.14 or less).
140 - Solaris 2.6 buggy PAM library
141 - Perl 5.004_03
142 - RedHat 6.1 (Authentication failure)
143 - RedHat 8.0 (Segmentation fault (core dumped))
