Add ldap_memfree(a); to your inner loop, like 'man ldap_first_attribute' says: NOTES The ldap_first_attribute() and ldap_next_attribute() return dynamically allocated memory that must be freed by the caller via ldap_memfree(3). This ITS will be closed. -- Regards, Hallvard

(ITS#4963) Sub-second ldap_search timeout accuracy
by cs＠unc.edu 14 May '07

14 May '07

Full_Name: Christian Schlatter Version: CVS HEAD (Mon May 14 15:21:36 EDT 2007) OS: ubuntu dapper URL: http://www.unc.edu/~cschlatt/openldap/result.patch Submission from: (NULL) (152.2.199.72) I'm developing an LDAP module for the OpenSER SIP server using OpenLDAP libldap. Since this is a real-time application I need to be able to set LDAP timeouts to a value less than a second. This isn't possible with the existing libldap ldap_result(...timeout...) implementation. In particular, the timeout check at the end of function wait4msg(..) in result.c only has an accuracy of one second. This lead to unexpected behavior for timeout values that are less than a second. I've added a patch for your consideration that adds sub-second accuracy to wait4msg. The code works for me but I don't have experience with the OpenLDAP source code and any coding guidelines. Nevertheless, I'd be very glad if this functionality could be incorporated in a future OpenLDAP release. Christian

(ITS#4962) inconsistent Bind(rootdn) behavior
by h.b.furuseth＠usit.uio.no 14 May '07

14 May '07

Full_Name: Hallvard B Furuseth Version: HEAD, RE23 OS: URL: Submission from: (NULL) (129.240.202.105) Submitted by: hallvard Backends are quite inconsistent about how Bind treats rootdn/rootpw. After a quick browse of the HEAD code, it looks like this - I'll investigate closer if needed: rootpw supported: Yes: config, bdb, meta, monitor, ldif, HEAD:null, sql, overlay retcode. No: dnssrv, ldap?, RE23:null, perl, relay, shell. (Bind not supported: passwd). Rootpw vs. normal Bind as rootdn (typically when rootdn names an entry): config, bdb, null, sql, overlay retcode (I think): Try rootpw first, then if failure try normal Bind (even if rootpw exists but the Bind password does not match it). ldif: Do not try rootpw if rootdn names an existing entry. meta: Fail if rootpw is missing or does not match, more complicated otherwise. monitor: Fine - there are no entries with passwords. The manpage is (fortunately:-) unclear on what happens in this case. Check if op->orb_method == LDAP_AUTH_SIMPLE: Yes: config, bdb, meta, monitor. No: ldif, null, sql, overlay retcode. Set op->orb_edn (op->oq_bind.rb_edn) from be_root_dn() on success: config, bdb, monitor, sql. Set op->orb_edn on failure: bdb: Sometimes, from &e->e_name. sql: Always, from op->o_req_ndn. Set rs->sr_err = LDAP_SUCCESS on success: ldif, meta Reset rs->sr_text: meta Which behavior is right? I'm wondering if Bind should fail if rootpw exists but the Bind password does not match it. In any case, methinks we need a be_rootpw_bind(op, rs) function which takes care of this consistently, so bi_op_bind in most cases can just do if (be_rootpw_bind(op, rs)) return rs->sr_err; If needed it could accept rs==NULL to just check the password - like be_isroot_pw() but with more return codes to distinguish different cases.

All these nodes have similar attribute except dn and cn. when i disable the code of the inner for loop. this problem appear less frequently. when i disable the code which get the attribute value of entry, in other word, both the for loop. this problem seems disappeared, but it maybe it will appear again if it is runed more times. // portion code of the program static int search_node_bydn(char *search_dn) { int ret; char *a = NULL, *attrs[10], *dn; char filter[1024]; LDAPMessage *e=NULL, *res = NULL; LDAP *ld = NULL; struct timeval timeout; // open the connection... // bind ... // then search the node.... attrs[0] = "objectGUID"; attrs[1] = "modifyTimeStamp"; attrs[2] = "cn"; attrs[3] = "sAMAccountName"; attrs[4] = "objectClass"; attrs[5] = "name"; attrs[6] = NULL; snprintf(filter, 1024, "(objectClass=*)"); timeout.tv_sec = 1000; system("ps aux | grep /myprogram"); ret = ldap_search_ext_s(ld, search_dn, LDAP_SCOPE_BASEOBJECT,filter, attrs, 0, NULL, NULL, &timeout, 0, &res); if (ret != LDAP_SUCCESS) { printf("search node %s error: %s\n", search_dn, ldap_err2string(ret)); ldap_msgfree(res); ldap_unbind_ext(ld, NULL, NULL); return (-1); } system("ps aux | grep /myprogram"); #if 1 // get the attribute value of entry. for (e = ldap_first_entry(ld, res); e != NULL; e = ldap_next_entry(ld, e)) { #if 1 BerElement *ptr = NULL; for (a = ldap_first_attribute(ld, e, &ptr); a != NULL; a = ldap_next_attribute(ld, e, ptr)) { // do sth with the attribute. }// inner for loop if(ptr != NULL) { ber_free(ptr,0); } #endif }// outer for loop #endif system("ps aux | grep /myprogram"); ldap_msgfree(res); res = NULL; system("ps aux | grep /myprogram"); ldap_unbind_ext(ld, NULL, NULL); return OK; }

Why not, I have basically nothing against -Q switch, but it would require a bit more changes in the current sources. I just needed something quick-and-not-so-dirty. Jan
