slurpd with SASL (ITS#655)
I was working on making slurpd work with more than simple authentication
since I wanted SASL authentication, so I made a quick patch in
the servers/slurpd/ tree that would allows the of use Kerberos V4 under
SASL when slurpd connects to slave servers. The patch is against
OpenLDAP 2.0 Beta, and is available at
It includes a short update to the slapd.conf(5) man page.
The patch does not include code to fetch a Kerberos service ticket from
the /etc/srvtab file, since that breaks the intent of SASL (which is to
free the application from having to write mechanism specific code).
Therefore, if a SASL mechanism that uses Kerberos (i.e. KERBEROS_V4 or
GSSAPI) is to be used, the slurpd process needs to run as the child of a
ticket refreshing program like "reauth" or "kauth".
The slapd.conf on the master slapd will need lines like
replica host=ldap2.andrew.cmu.edu \
and the slapd.conf on the slave will need an updatedn line that gives the
SASL name. Running slapd with -d128 will produce "acl_mask" lines that
tell the SASL name that the server applies to bound connections.

(The "access" line is provided just to show how SASL names can be put into
an ACL, and that the updatedn will probably be adding/removing entries and
