Connecting to LDAPS
by Marian Baskharoun 07 Nov '14

07 Nov '14

Hi, I created an iOS app using xcode version 6.0.1. This app should accept the windows login information from the user. I'm using OpenLDap to do the authentication. This is the code I'm using, works fine with Ldap and port 389 How do I make it work with Ldaps and port 636? # define LDAP_SERVER = "ldap://host:389" - (BOOL)checkValidUser:(NSString *)username password:(NSString *)password { LDAP *ld; int rc; int desired_version = LDAP_VERSION3; struct berval cred; size_t len = strlen([username UTF8String]) + 1; char usr [len]; memcpy(usr, [usernameUTF8String], len); size_t len2 = strlen([password UTF8String]) + 1; char passwd [len2]; memcpy(passwd, [password UTF8String], len2); cred.bv_val = (char *) passwd; cred.bv_len = strlen( passwd ); if( ldap_initialize( &ld, LDAP_SERVER ) ) { return NO; } rc = ldap_set_option(ld, LDAP_OPT_PROTOCOL_VERSION, &desired_version); if ( rc != LDAP_SUCCESS ) { perror( "ldap_set_option failed" ); exit(EXIT_FAILURE); } else { printf("Set LDAPv3 client version.\n"); } // Simple Authentication rc = ldap_sasl_bind_s( ld, usr, LDAP_SASL_SIMPLE, &cred, NULL, NULL, NULL ); if( rc != LDAP_SUCCESS ) { fprintf(stderr, "ldap_sasl_bind_s: %s\n", ldap_err2string(rc) ); return NO; } else { return YES; } } Thanks, Marian

Meaning of "ppolicy_bind: Setting warning for password expiry for ... = 0 seconds"?
by Ulrich Windl 06 Nov '14

06 Nov '14

Hi! Can someone explain what this message is actually saying: slapd[3990]: ppolicy_bind: Setting warning for password expiry for uid=testuser,ou=domain,dc=org = 0 seconds Does this mean a user who mistyped his password before logged in successfully now? I saw no change to the LDAP database after this message, so what is changed, and where is it cahnged? Also those "0 seconds" don't match my password policy, which looks like this (still testing): -- objectClass: namedObject objectClass: pwdPolicy cn: PP-Default pwdAttribute: userPassword pwdMinAge: 30 pwdMaxAge: 86400000 pwdInHistory: 3 pwdCheckQuality: 1 pwdMinLength: 8 pwdExpireWarning: 604800 pwdGraceAuthNLimit: 5 pwdLockout: TRUE pwdLockoutDuration: 1800 pwdMaxFailure: 10 pwdFailureCountInterval: 1209600 pwdMustChange: TRUE pwdAllowUserChange: TRUE pwdSafeModify: FALSE -- I'm running SLES11 SP3... Regards, Ulrich

Migrating from BDB to LMDB
by Michael 04 Nov '14

04 Nov '14

Good evening - I would like to upgrade my OpenLDAP servers and migrate from BDB to LMDB. What is the recommended path for doing this? Can I simply take a dump with slapcat while using BDB and then run a slapadd on the resulting LDIF after changing the configuration to MDB? -Mike

Trying to switch from bdb to mdb
by Jerry 04 Nov '14

04 Nov '14

I am running OpenLDAP on a FreeBSD-10 amd 64 machine. It is installed via the FreeBSD ports system and I compile it on my machine. I recently wanted to switch from BDB since versions greater than 6 are not acceptable to OpenLDAP. I wanted to use "mdb", but I just cannot seem to get it configured correctly. I changed the "database bdb" to "database mdb" but when I try to start openLDAP, I get this error: Starting slapd Unrecognized database type (mdb) Warning: failed to start slapd I removed the existing database, so it should be starting up with a clean environment, but the problem continues. This is probably a problem specific to FreeBSD. If any user of FreeBSD has this working, I would love to see how they configured it. Feel free to contact me off list if it is more convenient. Thanks! -- Jerry

Issue: slapd keeps crashing about twice a day on multiple servers. I updated the kernel and openldap but still see the problem. Anyone point me in the right direction?

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 hi, is there way to have something like, I'd call, "journal of changes" where it could be saved all changes (modifications and deletions in particular) for each object what I'm talking about is *whole* history of the actions the object has undergone after creation - -- Zeus V.

Windows Server 2012 R2 - TLS 1.2 connection errors
by Jeff Lebo 02 Nov '14

02 Nov '14

Have had a public facing OpenLDAP server setup pointing to Windows Server 2008 on the back end for auth. AD servers are being migrated to Server 2012 R2, and I see this error on the Windows side when OpenLDAP tries to authenticate to them: "An TLS 1.2 connection request was received from a remote client application, but none of the cipher suites supported by the client application are supported by the server. The SSL connection request has failed." "A fatal alert was generated and sent to the remote endpoint. This may result in termination of the connection. The TLS protocol defined fatal error code is 40. The Windows SChannel error state is 1205." I've spent the last few days trying different configs, and reading Microsoft forums, and haven't been able to figure it out. Apparently MS changed the TLS configs with 2012R2 and it doesn't support a key length I am using. I've tried to disable TLS 1.2 on the OpenLDAP side using TLSCiperSuite in slapd.conf, but OpenLDAP fails to start with "main: TLS init def ctx failed: -1".
