[Samba] how to enable Active Directory support building samba on AIX?

I don't really understand (yet) the contence of config.log :- (
There are #undefine statements for ldap_init, but I have no idea why.

Why does configure say "ldap_initialize : not found" when even I can see it
in
/usr/local/samba/samba-4.1.5/include/ldap.h:
...
/*
 * in open.c:
 */
#if LDAP_DEPRECATED
LDAP_F( LDAP * )
ldap_init LDAP_P(( /* deprecated, use ldap_create or ldap_initialize */
        LDAP_CONST char *host,
        int port ));

LDAP_F( LDAP * )
ldap_open LDAP_P((      /* deprecated, use ldap_create or ldap_initialize
*/
        LDAP_CONST char *host,
        int port ));
#endif

LDAP_F( int )
ldap_create LDAP_P((
        LDAP **ldp ));

LDAP_F( int )
ldap_initialize LDAP_P((
        LDAP **ldp,
        LDAP_CONST char *url ));

It IS there!!! Why does it not find it? - This slowly is driving me
crazy ;- ) It finds the other functions, why not init?
Or is this message wrong? Should it be "don't know how to handle" or
"function returned NULL or whatever"?

Anyway I've uploaded config.log to
https://bugzilla.samba.org/show_bug.cgi?id=10047 . I hope this is ok...


How do I set "-lldap -llber" correctly on LDFLAGS?

I have tried with
export LDFLAGS="-lldap -llber -L/usr/local/samba/samba-4.1.5/lib"

but I can't see any difference. Still the same error: "LDAP support ist not
available."

Maybe you could also post your build commands for ldap. I still think there
may be something wrong with it.

Thanks and regards
Peter

Hi Peter,
Could you have a look in bin/config.log and see what the build error is?
It should find ldap_init
I'm also on 7.1 ML02 using xlc 12.1
However I have -lldap -llber set as well on  LDFLAGS

  Hi

  unfortunatly I connot confirm that this patch works. Inserting the two
  lines with "headers='ldap.h...' does not make any difference.

  I'm using AIX 7.1 ML02, xlc 12.1.

  First I build openldap 2.4.39 into /usr/local/samba/samba-4.1.5. This
  seems
  to work correctly, there is no error with configure and make:

  ./configure --prefix=/usr/local/samba/samba-4.1.5 \
            --sysconfdir=/usr/local/samba/conf
  --localstatedir=/var/samba/openldap \
            --mandir=/usr/local/samba/samba-4.1.5/man --with-threads=no \
            --enable-null --enable-dnssrv --enable-bdb=no \
            --enable-static --enable-backends=no

  Then I configure samba with:

  export LDFLAGS=-L/usr/local/samba/samba-4.1.5/lib
  export CFLAGS=-I/usr/local/samba/samba-4.1.5/include

  waf configure --prefix=/usr/local/samba/samba-4.1.5 \
            --sysconfdir=/usr/local/samba/conf \
            --localstatedir=/var/samba/smb \
            --mandir=/usr/local/samba/samba-4.1.5/man \
            --with-privatedir=/usr/local/samba/conf \
            --with-configdir=/usr/local/samba/conf \
            --with-piddir=/var/samba/smb/pids \
            --with-logfilebase=/var/samba/smb/logs \
            --with-ldap \
            --with-ads

  configure DOES detect the library, it DOES detect the header files and
  even
  the variables which it checks are OK. It just DOES NOT detect the init
  (ialize) functions, although all is present in ldap.h:

  Checking for header ldap.h   : yes
  Checking for header lber.h   : yes
  Checking for header ldap_pvt.h  : no
  Checking for ber_tag_t     : ok
  Checking for library lber  : yes
  Checking for ber_scanf    : ok
  Checking for ber_sockbuf_add_io     : ok
  Checking for variable LDAP_OPT_SOCKBUF    : ok
  Checking for variable LBER_OPT_LOG_PRINT_FN     : ok
  Checking for library ldap   : yes
  Checking for ldap_init        : not found
  Checking for ldap_init_fd : not found
  Checking for ldap_initialize  : not found
  Checking for ldap_set_rebind_proc : not found
  Checking for ldap_add_result_entry  : ok
  Checking whether ldap_set_rebind_proc takes 3 arguments   : ok
  Active Directory support not available: LDAP support ist not available.
  /usr/samba-4.1.5/source3/wscript:753: error: Active Directory support not
  found. Use --without-ads for building without Active Directory support.

  I suspect the init function somehow is not working correctly, but I don't
  know how to check.


  Regards
  Peter

  Indeed!  I wasn't aware you had moved out of the AIX world.

  Thanks.
