RE: openldap-2.1.14 + ldapdb.c: slapd core dumped: gdb bt & truss
Thanks for the back-trace. I've patched this problem in CVS HEAD. Here's the
fix if you want to apply it to your own source:
diff -u -r1.74 -r1.75
--- saslauthz.c 16 Feb 2003 18:34:29 -0000 1.74
+++ saslauthz.c 1 Mar 2003 23:21:24 -0000 1.75

}
/* Allow the manager to authorize as any DN. */
- if( be_isroot( conn->c_authz_backend, authcDN )) {
+ if( conn->c_authz_backend && be_isroot( conn->c_authz_backend,
authcDN )) {
rc = LDAP_SUCCESS;
goto DONE;
}
Of course, the reason you tripped on this is because you didn't setup a
sasl-regexp map as explained in the ldapdb README file. Go read it.
