Introduction to Cyrus SASL
The Cyrus SASL package contains a
Simple Authentication and Security Layer, a method for adding
authentication support to connection-based protocols. To use SASL,
a protocol includes a command for identifying and authenticating a
user to a server and for optionally negotiating protection of
subsequent protocol interactions. If its use is negotiated, a
security layer is inserted between the protocol and the connection.

Installation of Cyrus SASL
Install Cyrus SASL by running the
following commands:
patch -Np1 -i ../cyrus-sasl-2.1.21-openldap23-1.patch &&
patch -Np1 -i ../cyrus-sasl-2.1.21-openssl98-1.patch &&
sed -i '/sasl_global/s/^static //' lib/client.c &&
sed -i 's/cat8/man8/' saslauthd/Makefile.in &&
./configure --prefix=/usr --sysconfdir=/etc \
--with-dbpath=/var/lib/sasl/sasldb2 \
--with-saslauthd=/var/run &&
make
This package does not come with a test suite. If you are planning
on using the GSSAPI authentication mechanism, it is recommended to
test it after installing the package using the sample server and
client programs which were built in the preceding step.
Instructions for performing the tests can be found at
http://www.linuxfromscratch.org/hints/downloads/files/cyrus-sasl.txt.
Now, as the root user:
make install &&
install -v -m755 -d /usr/share/doc/cyrus-sasl-2.1.21 &&
install -v -m644 doc/{*.{html,txt,fig},ONEWS,TODO} \
saslauthd/LDAP_SASLAUTHD /usr/share/doc/cyrus-sasl-2.1.21 &&
install -v -m700 -d /var/lib/sasl
Command Explanations
sed ... lib/client.c:
This command fixes an issue when compiling Cyrus SASL with GCC-4.
sed 's/cat8/man8/'
...: This command puts the saslauthd man page in a more standard
location.
--with-dbpath=/var/lib/sasl/sasldb2: This
parameter forces the saslauthd database to be created in
/var/lib/sasl instead of /etc.
--with-saslauthd=/var/run: This
parameter forces saslauthd to use the FHS compliant
directory /var/run for variable run-time
data.
--with-ldap: This parameter enables use
with OpenLDAP.
--enable-ldapdb: This parameter enables the
LDAPDB authentication backend. There is a circular dependency with
this parameter. See
http://wiki.linuxfromscratch.org/blfs/wiki/cyrus-sasl
for a solution to this problem.
install -v -m644 ...:
These commands install documentation which is not installed by the
make install command.
install -v -m700 -d
/var/lib/sasl: This directory must exist when
starting saslauthd.
If you're not going to be running the daemon, you may omit the
creation of this directory.
Configuring Cyrus SASL
/etc/saslauthd.conf (for
saslauthd LDAP
configuration) and /usr/lib/sasl2/Appname.conf (where "Appname" is
the application defined name of the application)
If you need to run the saslauthd daemon at system startup,
install the /etc/rc.d/init.d/cyrus-sasl
init script included in the blfs-bootscripts-20060910
package.
make install-cyrus-sasl
![[Note]](../images/note.png)
Note
You'll need to modify the init script and replace the
<authmech> parameter
to the -a switch with your desired
authentication mechanism.
