What I need is to have the “glue” items returned as part of the search.  It looks to me like I can get nodes that are “glue” nodes to be part of the results by commenting out these lines:

 

in src\servers\slapd\back-bdb\search.c,  lilnes 908-91

 

            if ( !manageDSAit && is_entry_glue( e )) {

                  goto loop_continue;

            }

 

If I comment out these lines, then I get the results I’m looking for.

 

Are there any other implications to the “glue” nodes?  It looks like I’m able to edit and delete these nodes as well.  But there is code in delete.c, modify.c, modrdn.c that worry about glue nodes.

 

Another option would be to redefine the is_entry_glue macro to always return false.  Is that a better approach?

Subject: entries exist in ldap (as glue entries), but are missing from the tree (v2.4.16)

 

Is this bug ITS#4626?  Or is there a workaround?

 

====

 

Using a build of 2.4.16 on RedHat linux; in a multi-master environment with 2 nodes.  On both nodes,  I have a tree that has a node “ou=Company, o=MyCompanyName”.  Under that are several nodes that are “glue” nodes.  Following those is a actual data node.

 

Slapd 2.4.16, built from source, running on redhat linux)

 

I have seen this occur several times on various test systems with similar configurations.   

 

The data in these nodes is inserted, in the proper order, (parent then children) using ldap client calls (ldap_add_s).  Later, when I go to look at the output of slapcat, I see that some nodes are replaced with “glue” nodes.

 

Questions:

1)       Why are these glue nodes created?  Is there a known bug that will cause existing nodes to be deleted without the children being deleted?  Is this an issue in replication?  (where syncrepl needs to create a node where the parent does not exist).  Is that why the glue nodes are created later?

2)       How can I change the “glue” to some other class?  Can that be done programmatically?

3)

This is a dump of slapcat (with unnecessary nodes removed)
