LDAP_OPT_DESC historic
by Michael Ströder 12 Sep '14

12 Sep '14

HI! What does it mean that there's the comment "historic" at constant LDAP_OPT_DESC in ldap.h? Is there another option value one should use to get the file descriptor of a connection? Ciao, Michael.

Multiple threads and mdb_dbi_open
by Harry B 11 Sep '14

11 Sep '14

Hello, As per the documentation here http://symas.com/mdb/doc/group__mdb.html#gac08cad5b096925642ca359a6d6f0562a I see the following, "This function must not be called from multiple concurrent transactions. A transaction that uses this function must finish (either commit or abort) before any other transaction may use this function." This seems to imply that after one txn has begun on an environment, I cannot create another txn or dbi until the first one has finished - that doesn't seem to be right. If I have multi-threaded app, what is the expected sequence for creation of Environment, Transaction, and DBI handles? Any help is appreciated. -- Harry

Re: Replication breaks and needs restart - version 2.4.30

Hello Quanah, Thanks for your suggestion. I will seriously consider upgrading my installations. For now, the issue seems resolved by setting TCP keepalive values in my servers. Regards, Raja.

question on ldap_unbind_ext_s
by Aditham, Radhakrishna 09 Sep '14

09 Sep '14

Hi, We have a long running server that tries to get a new LDAP handle if the current handle becomes invalid (LDAP_SERVER_DOWN error, etc). However if I call ldap_unbind_ext_s() on the old handle to release it, it hangs with the following stack: (gdb) bt #0 0x000000080166935c in read () at read.S:2 #1 0x00000008014748f0 in __read (fd=68, buf=0x803293003, nbytes=5) at /.automount/nfs.panwest.panasas.com/root/sb10/hlewis/hlewis-sb10-pioneer-ldap/src/freebsd-c/lib/libthr/thread/thr_syscalls.c:384 #2 0x0000000802c715d2 in sb_stream_read (sbiod=0x8088070d0, buf=0x803293003, len=5) at /.automount/nfs.panwest.panasas.com/root/sb10/hlewis/hlewis-sb10-pioneer-ldap/src/likewise/openldap/libraries/liblber/sockbuf.c:493 #3 0x0000000802c7207e in sb_debug_read (sbiod=0x803291220, buf=0x803293003, len=5) at /.automount/nfs.panwest.panasas.com/root/sb10/hlewis/hlewis-sb10-pioneer-ldap/src/likewise/openldap/libraries/liblber/sockbuf.c:827 #4 0x0000000802356971 in tlso_bio_read (b=0x803205400, buf=0x803293003 "\027\003\001", len=5) at tls_o.c:687 #5 0x000000080252c2df in BIO_read () from /usr/lib/libcrypto.so.1.0.0 #6 0x0000000802eb9f01 in ssl3_read_n () from /usr/lib/libssl.so.1.0.0 #7 0x0000000802eba3ce in ssl3_read_bytes () from /usr/lib/libssl.so.1.0.0 #8 0x0000000802eb67ac in ssl3_shutdown () from /usr/lib/libssl.so.1.0.0 #9 0x0000000802356cf6 in tlso_sb_close (sbiod=0x803291250) at tls_o.c:808 #10 0x0000000802c71253 in ber_int_sb_close (sb=0x803291160) at /.automount/nfs.panwest.panasas.com/root/sb10/hlewis/hlewis-sb10-pioneer-ldap/src/likewise/openldap/libraries/liblber/sockbuf.c:383 #11 0x000000080233d625 in ldap_free_connection (ld=0x804c48c00, lc=0x8088080f0, force=1, unbind=1) at request.c:769 #12 0x000000080232ffa2 in ldap_ld_free (ld=0x804c48c00, close=1, sctrls=0x0, cctrls=0x0) at unbind.c:93 #13 0x000000080232fe8b in ldap_unbind_ext (ld=0x804c48c00, sctrls=0x0, cctrls=0x0) at unbind.c:52 #14 0x000000080232fec5 in ldap_unbind_ext_s (ld=0x804c48c00, sctrls=0x0, cctrls=0x0) at unbind.c:61 ...... I want to make sure that there are memory leaks etc, hence the attempt to release the invalid handle. Question: What is the best or correct way to release an invalid LDAP handle? Appreciate any help. Thanks R.K. Aditham

Replication breaks and needs restart - version 2.4.30
by Raja T Nair 09 Sep '14

09 Sep '14

Hello All, I am running openldap-2.4.30 in multiple locations, and all are replicating from a single Provider. Though it seems working fine initially, the replication stops as time progresses. The only way to bring it back is to restart clients. Here are the relevant configuration lines from my provider and consumers: Provider: ----------- overlay syncprov syncprov-checkpoint 100 10 syncprov-sessionlog 100 Consumer: ----------------- syncrepl rid=203 provider=ldap://192.168.1.101:389 type=refreshAndPersist searchbase="dc=com" retry="120 3" attrs="*,+" scope=sub bindmethod=simple binddn="cn=user1,ou=people,dc=mydomain,dc=com" credentials="user1pass" It would be great if someone can help me with this situation. Currently I keep restarting every client, and it breaks the respective operation being served by the client every now and then. Thanks in Advance, Raja. -- :^)

Hi, Is there a way to count the total number of user objects in an AD forest. I do not want the names/details of any of these user objects. But I just want a programmatic way of finding the total number of AD users. Is it possible to achieve ? Could not get anything related from Googling. Thanks. -- Sankar P http://psankar.blogspot.com
