I'm experiencing crashes in slapd when attempting to bind via SASL using the OTP mech.

I'm using openldap version 2.3.39 for both slapd and my ldap utils (ldapsearch). I'm using the bdb backend.

I'm also using Debian Etch with the following versions of software:

Cyrus SASL 2.1.22(.dfsg1-8) libdb 4.2.52(+dfsg-2) libc6 2.3.6(.ds1-13etch2)

I've compiled cyrus sasl to use it's internal implementation of OTP, rather than OPIE:

--enable-otp (--with-opie is not enabled)

The problem I'm experiencing isn't when I successfully authenticate; that seems to work fine. It's when I run an ldapsearch, but instead of entering an OTP password, I press ctrl-c to cancel the search.

From the shell, when I perform an LDAP search, all appears normal:

hiro:~# ldapsearch -Y OTP -U abrown@olp.net SASL/OTP authentication started Challenge: otp-md5 497 hi3182 ext Please enter your one-time password:<ctrl-c> hiro:~#

However my slapd process dies.

Here's a gdb backtrace of the server process:

I've added a debug statement within slap_auxprop_store, so the openldap debug information below will include some additional information about what's being modified.

Here's output from an attempt that crashed (when I pressed ctrl-c in my ldapsearch):

If I enter a good OTP password, I get this in my logs:

If I enter an incorrect password, I get this:

So in the case where it's crashing, it appears the Cyrus SASL is attempting to revert the OTP entry back to the previous version to "unlock" it. I assume that the connection id of '-1' is relevant to the crash.

You should be able to reproduce this error with the following steps:

Compile SASL with OTP, but without OPIE

Configure a dummy SASL service configuration file, e.g.: hiro:~# cat > /usr/lib/sasl2/test.conf <<EOF > auxprop_plugin: ldapdb > ldapdb_uri: ldapi:/// > ldapdb_mech: EXTERNAL > EOF hiro:~#

Create a schema including an attribute of cmusaslsecretOTP, and create an entry in the directory which can use this attribute.

Configure slapd.conf with the appropriate sasl configuration to convert both the openldap user (connecting via ldapi:///) and the user specified in the ldapsearch, for example: sasl-regexp "gidNumber=0\+uidNumber=0,cn=peercred,cn=external,cn=auth" cn=admin,dc=olp,dc=net

sasl-regexp "uid=([^,]+),cn=otp,cn=auth" ldap:///ou=people,dc=olp,dc=net??one?(btcAltUid=$1)

Issue a saslpasswd2 to initialize the cmusaslsecretOTP attribute for the user:

hiro:~# saslpasswd2 -a test -n abrown@olp.net Password: Again (for verification):

The cmusaslsecretOTP attribute should look something like: md5 0499 hi8351 1c19abc81f35dc63 00000000000000000000

opiekey can be used to convert the OTP challenge into the appropriate response. For instance:

hiro:~# ldapsearch -Y OTP -U abrown@olp.net SASL/OTP authentication started Challenge: otp-md5 498 hi8351 ext Please enter your one-time password:

Using opiekey to obtain response:

dwhite@zek:~$ opiekey -5 -x 498 hi8351 Using the MD5 algorithm to compute response. Reminder: Don't use opiekey from telnet or dial-in sessions. Enter secret pass phrase: 556A 99B3 52FA CEB1

Feed the secret pass phrase back into ldapsearch for a successful bind.

To reproduce the bug, of course just kill the ldapsearch before entering any response.
