Re: (ITS#4982) link libldap_r explicitly with the threading libraries
by rra＠stanford.edu 21 Dec '07

Is there any further thoughts on this ITS? It's still open and it doesn't look like the patch has been applied, but it seemed like we'd reached a conclusion that it was the right thing to do. To recap, the problem is that libldap_r isn't being linked with the threading libraries, which means that when the linker builds the shared library, it doesn't have symbol versioning information available for the pthread functions and creates unversioned references. If the current ABI of the functions ever changes (as has happened in the past with glibc on Alpha), segfaults and other unpleasantness result. The patch adds the threading libraries to the link command for libldap_r so that the linker has the symbol versioning information available and can bind the pthread functions to the appropriate symbol versions in glibc, allowing the library to keep working using glibc's backwards compatibility support even if the current ABI changes again. -- Russ Allbery (rra(a)stanford.edu) <http://www.eyrie.org/~eagle/>

syncrepl (refreshAndPersist) fails after system date is moved backwards
by jan.cedergren＠nsn.com 21 Dec '07

21 Dec '07

Hello, I'm facing some problems with replication and hoping that someone could clarify how this case should work (is this a bug or a feature). Replication seems to work initially as expected but if I change the system date to something in the past (e.g. 1 year backwards) then the replication stops working. When I change back the current date (to the year that it initially was) then everything seems to work fine again. Is this kind of behaviour in LDAP a restriction that has to do with having timestamps in the CSNs or is this a bug? I tried to find this problem from the archives with no success. Br, -Jani

(ITS#5295) option to allow slapd bind to any available port

Full_Name: Chitra Vemkatramani Version: 2.3.27 OS: Redhat URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (162.83.178.28) For a project that we are using openldap in, we would like to allow multiple users to start up ldap servers on the same machine. We would like an option on the slapd command line asking the server to pick any available port to bind to. We can then do netstat, find the port and pass that on to the client. Here is the patch we put in, to allow us to specify -1 for the port, so that the server will pick any available port. Can you please consider adding this to the server options ? --- openldap-2.3.27/libraries/libldap/url.c 2006-04-03 15:49:55.000000000 -0400 +++ /homes/hny1/chitrav/bindport0/url.c 2007-04-19 12:26:47.407806503 -0400 @@ -833,7 +833,7 @@ ludp->lud_next = NULL; ludp->lud_host = NULL; - ludp->lud_port = 0; + ludp->lud_port = -1; ludp->lud_dn = NULL; ludp->lud_attrs = NULL; ludp->lud_scope = LDAP_SCOPE_DEFAULT; @@ -1118,7 +1118,7 @@ (*ludpp)->lud_host = NULL; } - if ((*ludpp)->lud_port == 0) { + if ((*ludpp)->lud_port == -1) { if( strcmp((*ludpp)->lud_scheme, "ldap") == 0 ) { (*ludpp)->lud_port = LDAP_PORT; #ifdef LDAP_CONNECTIONLESS --- openldap-2.3.27/servers/slapd/daemon.c 2006-05-11 14:33:31.000000000 -0400 +++ /homes/hny1/chitrav/bindport0/daemon.c 2007-04-19 12:35:25.814156154 -0400 @@ -683,7 +683,7 @@ struct sockaddr **sap; #ifdef LDAP_PF_LOCAL - if ( port == 0 ) { + if ( port == -1 ) { *sal = ch_malloc(2 * sizeof(void *)); if (*sal == NULL) return -1; @@ -866,12 +866,12 @@ return -1; } - if(! lud->lud_port ) lud->lud_port = LDAP_PORT; + if( lud->lud_port == -1 ) lud->lud_port = LDAP_PORT; #else l.sl_is_tls = ldap_pvt_url_scheme2tls( lud->lud_scheme ); - if(! lud->lud_port ) { + if( lud->lud_port == -1 ) { lud->lud_port = l.sl_is_tls ?

(ITS#5294) ldapdelete gives error when too many entries

Full_Name: Chitra Vemkatramani Version: 2.3.27 OS: Redhat URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (162.83.178.28) The ldapdelete command does not have a sizelimit option. If I have a lot of entries in my LDAP server and issue an ldapdelete command, the command fails saying that there are too many entries (default seems to be 500). It would be useful to have a -z <sizelimit> option for ldapdelete, as for ldapsearch, so that I can use ldapdelete to delete sets of entries at a time. thanks -Chitra

Full_Name: Chitra Venkatramani Version: 2.3.27 OS: Redhat URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (162.83.178.28) I added a set of entries to the LDAP server, with sub directories, such as -- dn: cn=aa,ou=chitrav,o=ibm.com dn: ou=bb,ou=chitrav,o=ibm.com dn: cn=bb1,ou=bb,ou=chitrav,o=ibm.com dn: ou=cc,ou=bb,ou=chitrav,o=ibm.com dn: cn=cc1,ou=cc,ou=bb,ou=chitrav,o=ibm.com when I tried to do an ldapdelete command with -r option, I get the following error for every entry in the server, although all the entries do get deleted. ldap_search: Server is unwilling to perform (53) additional info: critical control unavailable in context On looking at the ldapdelete.c source code, lines 390 and 391 say c.ldctl_oid = LDAP_CONTROL_SUBENTRIES; c.ldctl_iscritical = 1; Marking the iscritical flag to 0, makes the error go away. I am not sure what this control does. This seems like a bug though. If so, please let me know what the fix should be, and in which release it will be available. Please let me know if you need any more information. thanks -Chitra
