Re: (ITS#6963) test050: test failed - server 1 and server 2 configs differ

The difference is that on server2, 2 of the entries have objectClass: glue instead of their correct objectclasses. From the diffs, this affected cn=schema,cn=config and olcDatabase={0}config,cn=config. Looking at the logs, this happened because during a syncrepl_nonpresent pass, the UUIDs for these two entries didn't match the UUIDs sent from some other master, so syncrepl attempted to delete them. Generally this is normal - cn=schema,cn=config and olcDatabase={0},cn=config are always created automatically by each slapd, so naturally their UUIDs differ on each server. But, also generally, after the first refresh each consumer would modify their local entries and overwrite the UUIDs with the ones received from their provider. Not sure why this didn't happen this time around. (back-config explicitly prevents any attempts to delete both of these entries. When syncrepl fails to delete an entry, it does a modify to change the objectclass to glue, which explains how they got to their final state when the test aborted.) -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

I always do git pull before posting an ITS applying HEAD to make sure nothing came in after the error. Ciao, Michael.

Don't do that. The LDIF specification says that all LDIF elements are terminated by SEP (CR LF or LF). Anything not conforming to this is not valid LDIF. As usual, garbage-in-garbage-out.
