input error=-2
by Joe Friedeggs 04 Jun '10

04 Jun '10

I just recently noticed 'input error=-2' when running in debug mode, and in my logs (loglevel sync shell stats ber conns). It seems to occur (always) when the connection it closed. Anyone know what might cause this? Is it anything I should be concerned with? I am not sure when this started. I have made numerous changes over the past few weeks; too many to back out. Thanks, Joe >From DEBUG:: ber_get_next on fd 25 failed errno=0 (Success) connection_read(25): input error=-2 id=20, closing. connection_closing: readying conn=20 sd=25 for close connection_close: conn=20 sd=25 =>ldap_back_conn_destroy: fetching conn 20 daemon: removing 25 Similarly in log: Jun 4 15:39:31 ldapserver slapd[7683]: daemon: read active on 16 Jun 4 15:39:31 ldapserver slapd[7683]: conn=150 op=2 UNBIND Jun 4 15:39:31 ldapserver slapd[7683]: connection_read(16): input error=-2 id=150, closing.

ldap search bug
by Jeremiah Martell 03 Jun '10

03 Jun '10

Just pinging the mailing list again. I'm hoping someone has some advice or guidance on this. Thanks, - Jeremiah ---------- Forwarded message ---------- From: Jeremiah Martell <inlovewithgod(a)gmail.com> Date: Thu, May 27, 2010 at 3:42 PM Subject: ldap search hangs forever To: openldap-technical(a)openldap.org I'm using openldap-2.4.18 as a client to bind and asynchronously search an active directory server. I have a domain, example.com, that has two domain controllers: one.example.com, and two.example.com. The ip of one.example.com is 12.34.56.1 The ip of two.example.com is 12.34.56.2 The reverse mapping of 12.34.56.1 is one.example.com The reverse mapping of 12.34.56.2 doesn't exist ----- / nslookup one.example.com Server: 12.34.56.99 Address 1: 12.34.56.99 dns1.example.com Name: one.example.com Address 1: 12.34.56.1 one.example.com / nslookup two.example.com Server: 12.34.56.99 Address 1: 12.34.56.99 dns1.example.com Name: two.example.com Address 1: 12.34.56.2 / nslookup example.com Server: 12.34.56.99 Address 1: 12.34.56.99 dns1.example.com Name: example.com Address 1: 12.34.56.2 Address 2: 12.34.56.1 one.example.com / nslookup 12.34.56.2 Server: 12.34.56.99 Address 1: 12.34.56.99 dns1.example.com Name: 12.34.56.2 Address 1: 12.34.56.2 / nslookup 12.34.56.1 Server: 12.34.56.99 Address 1: 12.34.56.99 dns1.example.com Name: 12.34.56.1 Address 1: 12.34.56.1 one.example.com / ----- I have given openldap a "rebind proc" to use when chasing the referrals. I do a sasl gssapi bind to one.example.com, which succeeds. I do a search, which returns three referrals: DomainDnsZones.example.com ForestDnsZones.example.com example.com openldap looks up these three names and gets 12.34.56.2, which doesn't reverse map to anything. Then I get error messages for each referral: May 27 16:26:18 xyz: GSSAPI Error: Miscellaneous failure (see text) (Server (krbtgt/23.56.2(a)EXAMPLE.COM) unknown) May 27 16:26:18 xyz: GSSAPI Error: Miscellaneous failure (see text) (Server (krbtgt/23.56.2(a)EXAMPLE.COM) unknown) May 27 16:26:18 xyz: GSSAPI Error: Miscellaneous failure (see text) (Server (krbtgt/23.56.2(a)EXAMPLE.COM) unknown) Then openldap hangs forever; I never get a LDAP_RES_SEARCH_RESULT. ----- If I modify my DNS server to return 12.34.56.1 first instead of 12.34.56.2, then everything works perfectly. If I don't chase referrals, then everything works perfectly minus chasing referrals of course. If I use "normal" binding instead of sasl gssapi, then everything works perfectly. If I use openldap's syncronous search instead of asyncronously polling with ldap_result, then the call times out and returns. I half-expected openldap to not be able to bind to the referrals, but still fail quickly and return. I don't understand why the ldap search never finishes. (I never get a LDAP_RES_SEARCH_RESULT) I did get a LDAP_RES_SEARCH_REFERENCE and a LDAP_NO_RESULTS_RETURNED, but those dont signify the search has finished, right? I've attached the ldap debugging. You'll see at the end the repeated calls to ldap_result with timeouts of 10 seconds.

Syncrepl - ldap_bind: Invalid credentials error

syncrepl & history store
by Oliver Henriot 02 Jun '10

02 Jun '10

Dear OpenLDAP list users, I'm having syncrepl oddities. One of my consumer servers has an entry which is absent on the provider. I thought syncrepl would delete it during "present phase" mentioned in the admin guide but it's been sitting there for days and hasn't been removed. There is only one consumer on which this superfluous entry is present. I'm logging sync level on provider and consumers since I identified the problem and nothing odd appears. I unfortunately did not log sync level at the time the problem appeared so maybe I missed any useful info. The only thing I got in the logs when the problem occured was "deferring operation: too many executing" but I also sometimes get the same error in the logs and nothing bad happens to the data. I'm reading through the guide trying to understand what's going on and in the syncrepl section (http://www.openldap.org/doc/admin23/syncrepl.html ; yes I'm reading the version 2.3 documentation because I'm using the CentOS 5.5 packaged version : 2.3.43-12.el5) I've come across references to a history store maintained on the provider which is useful for the delete phase used in refreshAndPersist, which is what I am using. I thought this might be a plausible clue for my problem. However, nowhere else do I find any reference to this history store, how it's configured or how it works. Could the use of RefreshAndPersist explain the superflous entry present on one consumer and should(could) I configure a history store to solve this issue? Or should I switch to RefreshOnly to prevent this kind of problem from occuring again in the future? It's the first time I've come across it but when my directories will really be used they will be absolutely critical and I'd rather not have this kind of problem again if possible. Thanks for your help. Best regards, Oliver

replication issue
by Lennart Job 01 Jun '10

01 Jun '10

Hi there, I've got some problems with ldap replication. Ever since I've updated the master from Debian Etch to Lenny changes are no longer synced. I've got v2.4.11 running on both servers. The slave is still running Etch. SSL is active, so maybe there's a problem with the certificates... However, if I restart the slave slapd he does replicate properly. Do you know any reasons for this behavior? In addition, synchronization with samba on the master doesn't work properly anymore. I can create accounts but password changes don't take effect. So everybody has to use his first ever password to connect to samba... Thanks for your help! Kind regards, Lennart -- Lennart Job Ressort IT / Wissensmanagement fuks e.V.

LDAP C API

Hi there, I'm writing GTK application for managing LDAP directory, a kind of GTK variant of phpldapadmin. As for now I'm able to browse directory, objects' probepries and their values. What is not clear is how to figure out the RDN and Required property, and Structural value. How it is done? -- Покотиленко Костик <casper(a)meteor.dp.ua>

Server certificate
by Daniel Gomes 01 Jun '10

01 Jun '10

Hey there, I've got a simple enough question: is it possible to use a certificate for TLS (through the TLSCertificateFile directive) on which the FQDN of the LDAP server is not on the CN but instead on the alternative name? I tried this, but I'm getting a "TLS init def ctx failed: -64" and I thought it might be because of this issue. I also couldn't find a list of the error numbers and their descriptions, making it harder for me to understand what's wrong...
