389 Directory Server

389 Directory Server is a highly usable, fully featured, reliable and secure LDAP server implementation. It handles many of the largest LDAP deployments in the world.

All our code has been extensively tested with sanitisation tools. As well as a rich feature set of fail-over and backup technologies gives administrators confidence their accounts are safe.


The 389 Directory Server is subject to the terms detailed in the license agreement file called LICENSE.

Late-breaking news and information on the 389 Directory Server is available on our wiki page:


autoreconf -fiv
./configure --enable-debug --with-openldap --enable-cmocka --enable-asan
make lib389
sudo make install
sudo make lib389-install


make check
sudo py.test -s 389-ds-base/dirsrvtests/tests/suites/basic/

To debug the make check item's, you'll need libtool to help:

libtool --mode=execute gdb /home/william/build/ds/test_slapd
