Hi! Does the overlay accesslog "logops writes" on a consumer log changes made by syncrepl? I cannot see any log entries where changes are made, but maybe did something wrong. Hans

how to change userPassword in overlay...
by Marcin Giedz 02 Jul '07

02 Jul '07

Hi, Looking at smbk5pwd overlay I'm trying to build something similar. One of the attributes I need to change is userPassword for selected uid (not dn). In my LDAP tree I have several places where uid=user1 exists. Now I need to change userPassword for this user in all these places at once (through passwd). From my perspective EXOP_MODIFY_PASSWD is not suitable for me. So I though about creating overlay for this issue. I'm looking for low level operation for changing userPassword attribute with respect to previous password hash. Could anyone advise how can do this? Regards, Marcin -- ARISE M.Giedz, T.Żebruń sp.j. http: www.arise.pl mail: giedz(a)arise.pl tel: +48 502 537 157

trouble with slapd overlay
by Helmut Schulz 02 Jul '07

02 Jul '07

Hello all, hope I picked the appropriate mailing list ... I've got a problem with a slapd overlay I'm currently working at: the overlay causes slapd to bomb, when compiled for & running on Debian Etch AMD64 and Ubuntu Dapper (no other 64bit experiences so far), if - and only if so - it's response handler is invoked simultaneously in several threads. The error always occurs at the same code line, line 89, in file template_symtab.c: the memory location referred by 'symtab', which has been allocated immediately before by ch_malloc(), is obviously invalid. As long as only one single thread is hitting this code piece, everything is fine. In 32bit-environments, the overlay works. The overlay has (mutex-protected) critical sections of code: an overlay-specific cache, which, however, doesn't influcence the test behaviour (I usually deactivate it via config file directive (see inline comments in file template.c) to avoid the additional complexity). What I want to say: I almost for sure can exclude thread synchronization issues within my overlay as reason ... but somehow, the memory management seems to get confused, no clue why. I tried valgrind - it run's slapd fine, no sigsegv, no trouble, no related error messages. When the MALLOC_DEBUG_ environment variable is set, slapd runs great, too. Simple replacement of ch_malloc() and friends by stdlib malloc() and free() bypasses the problem as well. Maybe I've coded a memory overrun somewhere else within the overlay? Maybe I did not understand the slapd memory management API (which, seriously, seems to be a real pain! - I tried to use ch_malloc()/ch_strdup()/ch_free() where possible, use proper nesting of these functions - only exception was memory allocated by backend_attribute(), which I deallocate via ber_bvarray_free_x(), using the current thread's memory context). On the other hand, maybe the problem is related to ch_malloc() and the underlying memory management itself? The source code can be found here: http://www.thalion-graphics.de/download/template-overlay.tar.gz Would be very grateful for any advice. :) -- Helmut Schulz Thalion Graphic Solutions eK.

my overlay doesn't compile
by pkoelle＠gmail.com 02 Jul '07

02 Jul '07

Hi list, I played around to find out how overlays work but hit a brickwall when running make. The error is: liboverlays.a(statover.o):(.data+0x58): undefined reference to 'nestedgroup_initialize' collect2: ld returned 1 exit status nestedgroup_initialize is the initialization hook for my module (currently basically dynlist.c with some changes). I think I have added the relevant pieces to the build system (configure.in, servers/slapd/overlays/Makefile.in, include/portable.hin). Nevertheless, the linking error suggests there is still something missing. thanks Paul

Re: how to use slapo-refint (or why it doesn't work?)

I posted the whole slapd.conf 3 days ago but didn't see it appear on the list (a test installation, should be safe to post its slapd.conf) Also I have tested refint on different backend (tested bdb & hdb), and tested on different OS (also tested 2.3.27-25 on SuSE 10.2). Then, I tested to use manager as attribute as suggested by slapo-refint manual. None of them works. Do I need to export DB and slapadd all data back in order to activate this feature?
