SASL and slurpd

["MCGLADREY, KAYNE A" <KAYMCG@SAFECO.com>]

Hello everyone,

I am now 15 hours into the saga of installing OpenLDAP 2.0.11 on FreeBSD
4.3. Thanks to everyone who assisted in compiling the software - two typos
were to blame.  The successful sequence was:
1.Type env CPPFLAGS="-I/usr/local/include/sasl" LDFLAGS="-L/usr/local/lib
-L/usr/local/lib/sasl" ./configure --enable-login --disable-krb4
--disable-gssapi --with-des=/usr/include/openssl/ --without-kerberos
--disable-kpasswd --with-cyrus-sasl-includes=/usr/local/include/sasl/
--with-cyrus-sasl-libraries=/usr/local/lib/sasl/ and press Enter.
2.Type make depend and press Enter.
3.Type make and press Enter.
4.Type make install and press Enter.

However, I am now faced with the same issue I faced for 75 hours on Linux.
Presuming that this is the correct command to include SASL support, I would
like to use SASL authentication to secure the user name & password during
replication.  Data can travel over the wire in plain text.  I would IDEALLY
like to use MD5 to handle the SASL encryption.  However, as this email
states, none of the available methods (PLAIN, LOGIN, MD5) are working.

I have two servers, one running Red Hat 7.1 and one running FreeBSD 4.3.
Typing ldapsearch -d 2 on either server indicates that PLAIN and LOGIN are
supportedSASLMechnanisms.

To begin replication, I type the following command on the server:
/usr/local/libexec/slurpd -d 255

slurpd reads the configuration file without error and starts looking at the
replication log. Here is the output that concerns me:

Based on this output, it appears that the wrong user name is being passed.
Here is the relevant section of slapd.conf from the server:
## REPLICATION OPTIONS
replica host=jarrett.safeco.com:389
        binddn="uid=REPL.LDAP.SAFECO.COM"
        bindmethod=sasl
        saslmech=LOGIN
> > > NOTE: I've also tried "PLAIN" and "MD5".  Neither works. < < <
        authcID="REPL.LDAP.SAFECO.COM"
        authzID="REPL.LDAP.SAFECO.COM"
        realm=safeco.com
        credentials="password"

And from the backup server:
updatedn        "UID=REPL.LDAP.SAFECO.COM+REALM=JARRETT.SAFECO.COM"
updateref       ldap://ldap.safeco.com

And from the command sasldblistusers (also on the backup server):
user: REPL.LDAP.SAFECO.COM realm: jarrett.safeco.com mech: PLAIN
user: REPL.LDAP.SAFECO.COM realm: jarrett.safeco.com mech: CRAM-MD5
user: REPL.LDAP.SAFECO.COM realm: jarrett.safeco.com mech: DIGEST-MD5

Finally, here's the /usr/local/lib/sasl/slapd.conf (on the backup):
pwcheck_method: sasldb

Thank you for reading to the bottom of this rather comprehensive email.  If
you have a suggestion on how to make SASL work with OpenLDAP, please contact
me.
I will state again, for the record, that the following "suggestions" aren't
much help:
* "Check the archives for hints!"
* "Read the manpage for slapd.conf"
* "Check to see if the sample-client and sample-server with SASL are
working"
* "http://www.bayour.com/LDAPv3-HOWTO.html"; - this last one introduces WAY
too many variables, i.e. kerberos.  It's a great how-to, but it doesn't help
if you're trying to get _JUST_ SASL working.

Thanks in advance to those who reply,
