Also, I note that the glued paged response seems to work incorrectly. I made a simple test system, where the root database contains exactly one entry (the suffix) and a back-ldap is glued on top. If I request entries with a page size of 2, searching the suffix return 3 entries; subsequent searches return 2 entries from the proxy. I haven't figured out yet where the issue is. p.

LDAP bind using ldap_sasl_interactive_bind_s and DIGEST-MD5 fails the second time
by James Bong 01 Apr '10

01 Apr '10

I am currently using Mac OS X 10.6.2 and am attempting to use the ldap_sasl_interactive_bind_s API to do a digest-md5 authentication against Active Directory (2008, though I don't think it matters what flavor of AD is used). The bind works fine the first time. However, if I unbind and attempt to rebind as the same user, it fails with ldap_sasl_interactive_bind_s: Invalid credentials (49). If I bind with a different user, then unbind, and bind as the original user, it works. I created a simple program that illustrates the issue. When run, it binds correctly, unbinds, and then fails on the second bind: trying ldap_sasl_interactive_bind_s callback callback done ldap_sasl_interactive_bind_s Done Unbinding Unbound. ldap_sasl_interactive_bind_s callback callback done ldap_sasl_interactive_bind_s: Invalid credentials (49) additional info: 80090308: LdapErr: DSID-0C0904D1, comment: AcceptSecurityContext error, data 57, v1772 Any idea why it is not possible to use the same credentials twice? Here is the test program. I tried reinitializing the sasl library with sasl_done and sasl_client_init, but that doesn't seem to make a difference. #include <ldap.h> #include <sasl/sasl.h> #include <stdio.h> typedef struct sasl_defaults { char *mech; char *realm; char *authcid; char *passwd; char *authzid; } sasl_defaults; int callback(LDAP *ld, unsigned flags, void* defaults, void *interact ) { printf("callback\n"); sasl_interact_t *in_out=(sasl_interact_t *)interact; sasl_defaults *in_defaults=(sasl_defaults *)defaults; while (in_out->id !=SASL_CB_LIST_END) { switch (in_out->id) { case SASL_CB_USER: in_out->result=in_defaults->authcid; in_out->len=strlen(in_defaults->authcid); break; case SASL_CB_AUTHNAME: in_out->result=in_defaults->authcid; in_out->len=strlen(in_defaults->authcid); break; case SASL_CB_PASS: in_out->result=in_defaults->passwd; in_out->len=strlen(in_defaults->passwd); break; case SASL_CB_GETREALM: in_out->result=""; in_out->len=strlen(""); break; } in_out++; } printf("callback done\n"); return 0; } int main (int argv, char ** argc) { printf("trying\n"); for (;;) { LDAP *ld; ldap_initialize(&ld, "ldap://dc.ad.domain.com:389"); ldap_set_option(ld,LDAP_OPT_REFERRALS,LDAP_OPT_OFF); int version=3; ldap_set_option( ld, LDAP_OPT_PROTOCOL_VERSION, &version ); int timelimit=5; if (ldap_set_option( ld, LDAP_OPT_TIMELIMIT, (void *) &timelimit ) != LDAP_OPT_SUCCESS ) { printf("err\n"); return -1; } sasl_defaults defaults; defaults.mech = "DIGEST-MD5"; defaults.passwd="password"; defaults.authcid="user"; defaults.realm="realm.com"; defaults.authzid="user"; printf("ldap_sasl_interactive_bind_s\n"); int rc=ldap_sasl_interactive_bind_s( ld, NULL,defaults.mech, NULL, NULL, LDAP_SASL_QUIET, callback, &defaults ); if( rc != LDAP_SUCCESS ) { ldap_perror( ld, "ldap_sasl_interactive_bind_s" ); ldap_unbind(ld); return -1; } printf("ldap_sasl_interactive_bind_s Done\n"); printf("Unbinding\n"); ldap_unbind(ld); printf("Unbound.\n"); sleep(5); } }

(ITS#6504) Corrupted control value when using pagedresults with subordinate *ldap* database
by jonathan＠phillipoux.net 01 Apr '10

01 Apr '10

Full_Name: Jonathan Clarke Version: RE24 OS: URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (193.57.67.241) This is similar to ITS #5191 (http://www.openldap.org/its/?findid=5191), except it happens with a subordinate LDAP database. Consider this configuration : 8<--------------------------------------- database ldap suffix "o=test,o=sub" uri "ldap://localhost:1234" subordinate idassert-bind mode=none bindmethod=simple flags=prescriptive timeout=0 network-timeout=0 binddn="cn=svc,o=test" credentials="verysecret" idassert-authzFrom dn.regex:.* single-conn yes overlay rwm rwm-suffixmassage "o=test,o=sub" "o=test" database null suffix "o=sub" rootdn "cn=Manager,o=sub" rootpw secret overlay glue 8<--------------------------------------- A search with pagedResults control returns results as expected, but with a response control containing some garbage: result: 0 Success control:: qOEpCDg0MC4xMTM1NTYuMS40LjMxOSBmYWxzZSBNSVFBQUFBSkFnRUFCQVFFQUFBQQ== Some gdb'ing shows that backglue copies over the pointers to rs->sr_ctrls into glue_state->ctrls. But then, back-ldap's ldap_back_search does a ldap_controls_free() on rs->sr_ctrls. And so, the returned control contains garbage (mostly). I haven't been able to come up with a patch yet, just commenting line 454 of back-ldap/search.c works. Running out of time for now...

Full_Name: Barry Colston Version: 2.4.21 OS: Fedora 12 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (209.255.208.210) When a consumer slapd is started, if the provider slapd has had only Add operations performed while the consumer slapd was down, the provider slapd sends the consumer slapd the entryUUIDs of all records in the provider database. Note: this is not a list of all records that have been added/changed/deleted since the previous synchronization based on the consumer's contextCSN, it is a list of all records in the LDAP database (for some of our customers, this is 10,000,000 entryUUIDs that are returned to the consumer slapd.) The scenario to reproduce this problem is: 1. Start provider slapd 2. Start consumer slapd 3. Ensure that provider contextCSN matches consumer contextCSN 4. Shutdown consumer slapd 5. Add records to provider slapd (1 record is sufficient to create the problem) 6. Start consumer slapd with debug turned on (so the messages being sent can be viewed). The consumer slapd receives 1 to N LDAP_RES_INTERMEDIATE SYNC_ID_SETs (message type = 121) containing the entryUUIDs of the records in the provider's database, followed by a LDAP_RES_SEARCH_ENTRY, LDAP_SYNC_ADD (message type = 100) message for each record added to the provider, then finally a LDAP_RES_INTERMEDIATE, REFRESH_PRESENT message (message type = 121) message containing the provider's sync cookie. I am running OpenLDAP 2.4.21 with Berkeley 4.6.21 (with all patches) on Fedora 12. Running sync replication in RefreshAndPersist mode. Note: if at least 1 Modify or Delete operation is performed against the provider slapd while the consumer slapd is down, when the consumer slapd is started, the provider slapd does NOT send the Sync ID sets containing the entryUUIDs of all records in the provider database.
