RE: ldap_set_option() parameters

I looked at the page on the knowledgecenter for ldap_set_option.
It says you can set LDAP_OPT_REFERRALS using LDAP_OPT_ON or LDAP_OPT_OFF.

When I looked in QSYSINC/H(LDAP) I found these definitions:
#define LDAP_OPT_ON 0x01
#define LDAP_OPT_OFF 0x00

Which leads me to believe you could try a char instead of an int(10).
Dcl-s debugOffValue Char(1) Inz(x'00');



Also, there appears to be a difference depending on your version of LDAP.

OptionValue - (Input) The address of the value. For LDAP V3 client options, optionValue is the actual value to be set.

So with LDAP V3 you send the value, otherwise you send the address.

Subject: ldap_set_option() parameters

Hi,

I'm trying to set the LDAP_OPT_REFERRALS option off but I keep running
into a "Bad parameter to an ldap routine" error. I've searched the
archives and found two similar questions bu not answers. Doesn't mean the
aren't there I just can't find them so I'm asking too.

IBM's documentation has the following interface:


int ldap_set_option(
LDAP **ld*,
int *optionToSet*,
const void **optionValue* )


I have the following prototype defined:

D ldap_set_option...
D PR 10I 0 EXTPROC('ldap_set_option')
D ldapPointer * value
D LDAP_OPT_REFERRALS...
D 10I 0 value
D ldapOptValue * CONST

D LDAP_OPT_REFERRALS...
D S 10I 0 inz(2)
D ldapOptValue S *
D debugOffValue S 10I 0 inz(0)

/free
.
.
.
debugOffValue = ldapDebugOff;
ldapOptValue = %addr(debugOffValue);
returnCode = ldap_set_option(ldapPointer:
LDAP_OPT_REFERRALS:
ldapOptValue);
.
.
.
/end-free

I've tried other combinations but I keep receiving a return code value of
89 with a message text of "Bad parameter to an ldap routine".

Using

D ldapOptValue * value

results in the same error

What parameter is bad? I can't tell. My guess is parameter 3.

A trace dump is of no use.

ldap_start_operation: ld->ld_ref_count(1)
ldap_end_operation: ld->ld_ref_count(0)
ldap_err2string: err(89)


Does anyone see anything wrong with the way I set up the prototype?

Any suggestions?
