{SSHA} for PHP
by Jack van Rock 01 Dec '08

01 Dec '08

Hi, I want to modify a website-login-system (PHP) to check passwords which are deocoded with SSHA. My script should compare the clear password, which I get from a FORM, with the SSHA-hash of the password, which is in the database (MySQL). The dates in the MySQL-DB comes from a LDAP. This is my script: <?php $password_sub = "test"; //Das Passwort erhalte ich über ein HTML-Formular $passsowrd_hash_db = base64_decode("e1NTSEF9aH...."); //Diesen base64-Hash erhalte ich aus der Datenbank. //Er wird gleich decodiert, da man daraus das $salt benötigt. //Dann hat er die Form {SSHA}hxtMi.... $salt = base64_decode(substr($passsowrd_hash_db , 32)); //Berechnung des $salt $hash = "{SSHA}" . base64_encode(pack("H*", sha1($password_sub.$salt)).$salt); ?> But the script doesn't work, because the generated hash isn't the same as the hash from the database. But I don't now, what's wrong? May someone help me? m@xx

Some servers are delay synced...
by Bad Guy 01 Dec '08

01 Dec '08

Dear sir, We have got a N-way master (N=4) openldap running in version 2.4.11 under linux environment. The 4 servers can be synced immediately. However, after running for several hours, 2 of the servers are synced immediately while the other 2 servers are synced after around 60 mins. Scenairo : - Server 1, 2, 3, 4 are synced. After running for several hours, the following symptoms occur : - update record in server 3, server 4 will be updated immediately, but server 1 and server 2 got the update 1 hour later. - update record in server 4, server 3 will be updated immediately, but server 1 and server 2 got the update 1 hour later. - update record in server 1, server 2 will be updated immediately, but server 3 and server 4 got the update 1 hour later. - update record in server 2, server 1 will be updated immediately, but server 3 and server 4 got the update 1 hour later. Server 1 and server 2 are in same LAN segment, server 3 and server 4 in another LAN segment. There are firewalls between server 1/2 and server 3/4, but for same LAN segment, no firewall in between, only firewall in between different LAN segment. Any idea for this 1 hour delay synced ? Every server are config with syncrepl as shown below : bindmethod=simple binddn="cn=Manager" credentials=secret searchbase="o=ABCDE" schemachecking=off type=refreshAndPersist attrs="*,+" retry="1 +" # Performance tuning directives sizelimit 5000 threads 50 idletimeout 0 cachesize 10000 checkpoint 256 15 Also, from the LDAP log, it shows a lot of "cmp -1, too old" message. Also, from the log, some error message like the following is found : server01 slapd[6386]: do_syncrep2: rid=004 (-1) Can't contact LDAP server server01 slapd[6386]: do_syncrepl: rid=004 retrying server01 slapd[6386]: syncrepl_entry: rid=004 LDAP_RES_SEARCH_ENTRY(LDAP_SYNC_ADD) server01 slapd[6386]: syncrepl_entry: rid=004 be_search (0) server01 slapd[6386]: syncrepl_entry: rid=004 cn=test1,ou=test,o=ABCD server01 slapd[6386]: syncrepl_entry: rid=004 be_modify (0) Any idea on this ?

schema design and schema restrictions
by Mansour Al Akeel 27 Nov '08

27 Nov '08

Hello all, I an new to LDAP, and I have a need to migrate the existing system to ldap as this will ease a bit the management for the new system implementation. I need to authenticate users for a web site, and for the internal system ( linux, windows stations .... etc). Now the available account objectclass is structural so I can not user inetorgperson with account as both are structural. In this case I decided to extend inetOrgPerson, and add username and password as a MUST attributes. This is because all the users have access to the web site and they need authentication, but some users will need to have access to the machines. In this case I will create a new objectClass (ie. accountInfo) which containts the info I need (home directory, shell, loginScript, .... etc). The issue here is how do I restrict the accountInfo to be added under User ? This is in fact not only specific to this senario. I couldn't find any docs about how to prevent objectClass domain to be added under group ! Finally, how do other ldap admin deal with similar cases ? Any advice ? thank you.

Tracking down persistent OpenLDAP corruption
by Gilbert Wilson 26 Nov '08

26 Nov '08

So... I'm having a problem with persistent corruption in Apple's Open Directory. I believe this corruption is related to OpenLDAP and the BerkeleyDB. I was hoping that folks here might be able to help me track down whether this is the problem or not. Essentially, what is happening is that user accounts will "disappear" from workgroup manager and dscl[1]. Accounts that have maintained a persistent connection will continue to be authenticated. But, accounts that are not authenticated will be unable to authenticate. The Directory Administrator account, for example, cannot authenticate at these times. If I restart slapd, all the missing accounts that had persistent connections will no longer be able to authenticate. An LDIF export, however, will show that the accounts are all still there. A regular repair and a catastrophic repair of of the BerkleyDB does not work.[2] The first time this happened, it DID work, but subsequent events have not been so easily fixed. A restore from backup is the only way to fix it. However, I suspect that there is malformed data lurking somewhere in the OpenLDAP system. The backups all have this malformed data. Thus, it doesn't take very much for the system to get corrupted again. A hard shutdown does it every time, and a minor upgrade to the OS did it, too. The standard suggested fix is destroy and rebuild the Open Directory setup. For obvious reasons, I would like to avoid this. I want to know *what* is happening. If it is, in fact, malformed data that is becoming corrupt, *what* data should I be examining, *where* is it located, and *how* do I check it for anomalies? Has anyone else had this kind of persistent corruption of their LDAP system? What was causing it? How did you find it? Any leads or words of wisdom would be greatly appreciated.
