Dear Technical of openLDAP,
I use OpenLDAP development on the Mac platform, run into the following 2 questions, find a lot of information, still not resolved. Could you help me, Thank you.
1. Referrals error, Code flow: ld = ldap_init(host, port); rc = ldap_set_option(ld, LDAP_OPT_PROTOCOL_VERSION, &version); rc = ldap_set_option(ld, LDAP_OPT_REFERRALS, LDAP_OPT_ON); rc = ldap_set_rebind_proc(ld, bind_prompt, NULL); rc = ldap_set_option(ld, LDAP_OPT_SIZELIMIT,&sizelimit); rc = ldap_simple_bind_s(ld, adminDN, adminPwd); rc = ldap_search_s(ld, findDN, LDAP_SCOPE_ONELEVEL, [filter UTF8String], attrs, 0, &result);
CallBack function： static int bind_prompt(LDAP *ld,LDAP_CONST char *url,ber_tag_t request, ber_int_t msgid, void *params) { static char *dnsuffix; static char dn[256],password[256]; int authmethod; NSLog(@"rebind for request=%ld,msgid=%ld,url="">,request,(long)msgid,url); authmethod = LDAP_AUTH_SIMPLE; NSLog(@"re-bind dn?"); strcat(dn, dnsuffix); if (authmethod == LDAP_AUTH_SIMPLE && dn[0] != '\0') { NSLog(@"re-bind password?"); } else { password[0] = '\0'; } return ldap_bind_s(ld, dn, password, authmethod); }
Description of the problem:ldap_search_s() return value is 10, which is LDAP_REFERRAL,an it did not call the function “bind_prompt()”.
2. Kerberos error, Code flow： ld = ldap_init(host, port); rc = ldap_set_option(ld, LDAP_OPT_PROTOCOL_VERSION, &version); rc = ldap_set_option(ld, LDAP_OPT_REFERRALS, LDAP_OPT_OFF); rc = ldap_set_option(ld, LDAP_OPT_SIZELIMIT,&sizelimit); rc = ldap_set_rebind_proc(ld, bind_prompt, NULL); rc = ldap_bind_s(ld, adminDN, adminPwd, LDAP_AUTH_KRBV4);
Description of the problem:LDAP_AUTH_KRBV4,LDAP_AUTH_KRBV41,LDAP_AUTH_KRBV42,ldap_bind_s return value is -6, which is LDAP_AUTH_UNKNOWN.
Windows Client with the same configuration connected to openLDAP server successfully. Does my code or interface call for errors.
Regards! Aimee He
