(ITS#5002) Windows Service: logoff causes shutdown
by mark.lakes＠alcatel-lucent.com 07 Jun '07

07 Jun '07

Full_Name: Mark Lakes Version: 2.1.22 OS: Windows URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (198.206.187.100) Summary: LDAP service stops when user logs off. The LDAP server is registered as a Windows Service and works correctly with SCM. It is registered as an automatic service so should be running all the time. When a user logs off from the box, the logoff triggers the service to stop running. This happens on WindowsXP and Windows 2003 Server that are configured on a Domain. I have a solution. The problem is that despite the fact it is a service, it receives an event called CTRL_LOGOFF_EVENT. Since it is not handling this event, the default behavior by Windows is to shutdown the service. Add the following code to the source at an appropriate place(probably somewhere in ntservice.c) for when it runs as a service: /** This is used to handle CTRL_LOGOFF_EVENT from shutting us down when we are running as a service. Return TRUE works. We dont really care what the crtlType is. */ BOOL WINAPI WinSigHANDLER_ROUTINE(DWORD ctrlType) { /* char logstr[256]; sprintf(logstr, "NTservice: caught signal(%d)\n", ctrlType); writeStatusLog(logstr); switch (ctrlType) { case CTRL_LOGOFF_EVENT: ... default: } */ return TRUE; } Then, register the above function in the appropriate place as follows: SetConsoleCtrlHandler(WinSigHANDLER_ROUTINE, TRUE);

(ITS#5001) Incorrect SSF display
by quanah＠OpenLDAP.org 07 Jun '07

07 Jun '07

Full_Name: Quanah Gibson-Mount Version: 2.3.35 OS: NA URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (71.202.148.128) I was playing with SASL connections on an TLS encrypted connection, and noticed the SSF displayed is not correct in the SASL part. Jun 7 12:51:27 ldap-dev1 slapd[11858]: conn=4494 fd=29 TLS established tls_ssf=256 ssf=256 Jun 7 12:51:27 ldap-dev1 slapd[11858]: conn=4494 op=4 BIND dn="uid=quanah,cn=accounts,dc=stanford,dc=edu" mech=GSSAPI ssf=56 I believe that the second line above should really display "sasl_ssf=56", or probably even better, "sasl_ssf=56 ssf=256", similar to how the first line has "tls_ssf=256 ssf=256", so that it is clear that there are different security factors in play here. --Quanah

This is most likely the same as ITS#4957 which has already been fixed in the new release candidate.

Hi Pierangelo; Unfortunately I reproduced the problem with the HEAD dated June 5. If I do not add a rootdn to the monitor database, slapd cannot start. At the end of the log I find : monitor_back_register_entry_attrs(""): base="cn=databases,cn=monitor" scope=one filter="(namingContexts:distinguishedNameMatch:=c=fr)": unable to find entry ====> bdb_cache_release_all backend_startup_one: bi_db_open failed! (-1) slapd shutdown: initiated ====> bdb_cache_release_all bdb_db_close: alock_close failed slapd destroy: freeing system resources. slapd stopped. connections_destroy: nothing to destroy. Is the rootdn mandatory for monitor ? Best Regards Ali

Re: (ITS#4629) slapd failure on HP-UX 11.23/IA 64-bit
by h.b.furuseth＠usit.uio.no 04 Jun '07

I've been looking rather belatedly at this patch... it's simple, but the type name ACCEPT_TYPE_ARG3 is a bit ugly to use in .c source files instead of socklen_t. What's the "nice" way to do this? It's an internal type dependent on compiler switches (-D_XOPEN_SOURCE_EXTENDED on HP-UX), so I don't think it is wise to expose it in lber_types.h. It depends on <sys/socket.h> anyway. If not... just use ACCEPT_TYPE_ARG3 or maybe AC_SOCKLEN_T directly in .c files? #define AC_SOCKLEN_T in portable.h and typedef ac_socklen_t as it in sys/socket.h? Cheat and #define ber_socklen_t in portable.h? Also the patch is incomplete, we need to use this type (or some configured type) in getpeername(), getsockopt() and recvfrom() too. I _hope_ they all use the same type or at least a type with the same size on all these platforms... Googling around a bit, the mess with socklen_t and accept() prototypes seems amazing. I'm not sure I dare commit a patch which fails if it doesn't figure out the right type. At least not to RE23 - I'll commit a patch there which just guesses socklen_t or int if it can't figure out the right prototype. We can try one which fails in that case in HEAD and see if anyone complain. If we are going to be as paranoid as some other code out there, it'd be something like this (and even more if we want to try until succeeding in HEAD) - that's 12 compiles instead of the 5 in the submitted patch. Quite a lot... dnl socklen_t-like type in accept(), default socklen_t or int: dnl - The OS might define socklen_t without using it. POSIX moved from dnl int to size_t to socklen_t, hoping to stay at a 32-bit type, and dnl HP-UX has selectors for what to use. dnl - On Solaris 2.8 the prototype has void *len, but the default is OK. AC_MSG_CHECKING([for socklen_t-like type in accept()]) AC_CACHE_VAL(ol_cv_type_lber_socklen_t, [ set socklen_t int unsigned "unsigned long" long size_t test "$ac_cv_type_socklen_t" = yes || shift ol_cv_type_lber_socklen_t=$1 guessing="guessing " for lentype in "$@" ; do for addrtype in "struct sockaddr" void ; do AC_COMPILE_IFELSE([AC_LANG_PROGRAM([$ac_includes_default #ifdef HAVE_SYS_SOCKET_H #include <sys/socket.h> #endif extern int accept(int s, $addrtype *ap, $lentype *lp); ], [ $lentype len; accept(0, (struct sockaddr *) 0, &len); ])], [ol_cv_type_lber_socklen_t=$lentype guessing= ; break 2]) done ; done]) AC_MSG_RESULT([$guessing$ol_cv_type_lber_socklen_t]) AC_DEFINE_UNQUOTED(LBER_SOCKLEN_T, $ol_cv_type_lber_socklen_t, [define to socklen_t-like type in accept()]) -- Regards, Hallvard

HEAD is working as expected (slapd starts, although it cannot register the database specific monitor info). If a rootdn is added to the monitor database, it starts just fine. What version are you testing? Since this is a > 2.3 specific feature, anything earlier than HEAD will not be considered. p. Ing.
