Cyrus SASL-2.1.20

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.

Package information

Installation of Cyrus SASL

Install Cyrus SASL by running the following commands:

./configure --prefix=/usr --sysconfdir=/etc \
            --with-dbpath=/var/lib/sasl/sasldb2 \
            --with-saslauthd=/var/run &&

Now, as the root user:

make install &&
install -v -m644 saslauthd/saslauthd.mdoc \
    /usr/share/man/man8/saslauthd.8 &&
install -v -d -m755 /usr/share/doc/cyrus-sasl-2.1.20 &&
install -v -m644 doc/{*.{html,txt,fig},ONEWS,TODO} \
    saslauthd/LDAP_SASLAUTHD /usr/share/doc/cyrus-sasl-2.1.20 &&
install -v -d -m700 /var/lib/sasl

Command explanations

--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.

install -m644 ...: These commands install documentation which is not installed by the make install command.

install -d -m700 /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

Config Files

/etc/saslauthd.conf (for LDAP configuration) and /usr/lib/sasl2/Appname.conf (where "Appname" is the application defined name of the application)

Configuration Information

See file:///usr/share/doc/sasl/sysadmin.html for information on what to include in the application configuration files. See file:///usr/share/doc/sasl/LDAP_SASLAUTHD for configuring saslauthd with LDAP.

Init Script

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-6.0 package.

make install-cyrus-sasl


You'll need to modify the init script and replace the [authmech] parameter to the -a switch with your desired authentication mechanism.
