Hi there. We've been using OpenLDAP with back-sql to present data from MySQL for quite some time, and everything's been working great, including SASLv2 binds.
Due to a recent requirement for read/write capability (and future development) we're switching to a PostgreSQL backend instead. Everything works okay, except that the slapd process hangs indefinitely (when launched in the background) or segfaults (when launched with -d n) if SASL authentication is attempted. Simple auth works fine. Here are the last few lines from the slapd debug output: <==backsql_search() <==slap_sasl2dn: Converted SASL name to cn=nels lindquist,o=maei,c=ca slap_sasl_getdn: dn:id converted to cn=nels lindquist,o=maei,c=ca SASL Canonicalize [conn=7]: slapAuthcDN="cn=nels lindquist,o=maei,c=ca" SASL Canonicalize [conn=7]: authzid="nels" SASL proxy authorize [conn=7]: authcid="nels" authzid="nels" I also managed to get a backtrace from gdb: [Switching to Thread -1228420176 (LWP 17259)] 0x0018977b in strlen () from /lib/tls/libc.so.6 (gdb) bt #0 0x0018977b in strlen () from /lib/tls/libc.so.6 #1 0x00157611 in vfprintf () from /lib/tls/libc.so.6 #2 0x00178d14 in vsnprintf () from /lib/tls/libc.so.6 #3 0x080f4e58 in lutil_debug (debug=7, level=1191210597, fmt=0x810ce5c "==>slap_sasl_authorized: can %s become %s?\n") at debug.c:83 #4 0x0808fb77 in slap_sasl_authorized (op=0x9777138, authcDN=0xb6c7c678, authzDN=0xb6c7c670) at saslauthz.c:2074 #5 0x08093889 in slap_sasl_authorize (sconn=0x9776370, context=0xb7580a18, requested_user=0x9776c80 "nels", rlen=4, auth_identity=0x9776d81 "nels", alen=4, def_realm=0x0, urlen=0, props=0x97775f8) at sasl.c:697 #6 0x00b7283e in sasl_server_new () from /usr/lib/libsasl2.so.2 #7 0x00b72e3f in sasl_server_step () from /usr/lib/libsasl2.so.2 #8 0x0809450b in slap_sasl_bind (op=0x0, rs=0x9776370) at sasl.c:1380 #9 0x08072718 in fe_op_bind (op=0x9777138, rs=0xb6c7c870) at bind.c:276 #10 0x08071d99 in do_bind (op=0x9777138, rs=0xb6c7c870) at bind.c:200 #11 0x0805bd4c in connection_operation (ctx=0xb6c7c8f0, arg_v=0x9777138) at connection.c:1061 #12 0x080d71a2 in ldap_int_thread_pool_wrapper (xpool=0x97246b0) at tpool.c:485 #13 0x00960dd8 in start_thread () from /lib/tls/libpthread.so.0 #14 0x001edd2a in clone () from /lib/tls/libc.so.6 Any advice would be much appreciated! ---- Nels Lindquist <*> Information Systems Manager Morningstar Air Express Inc.
