hello,
(note: english is not my primary language. I'll do my best to be clear...)
I have scripts to test several replication scenarii, that setup the LDAP environment then allow me to play with parameters as I see fit.
I believe that there is a bug with the "seed replication" that allow one to build an exact clone of a master with minimal configuration on the slave side.
Before I fill an ITS, I'd like to confirm with you that I do the right thing (tm)
note: the tests below require 2 VMs, or running the two slapd instances in chroots, because a clone replica requires the data files to be in the same path...
this is openldap 2.4.39 on debian squeeze
I attach a script to replicate the problem. it requires root (it uses chroots)
use 0start.sh to: - create a ldap server to be served on ldap://localhost:3890 - start the master in chroot (the logs are in /jclain-slapd-test/master.data/slapd.log) - create a seed ldap replica to be served on ldap://localhost:3891 with ldap://localhost:3890 as the provider - start it in chroot with option -c rid=0 (the logs are in /jclain-slapd-test/slave.data/slapd.log)
use 1stop.sh to: - stop the servers - umount the chroots
If I understand the manual correctly, after 0start.sh, the replica should be identical to the master thanks to -c rid=0 BUT, the log on the replica says:
534d5481 dn_callback : new entry is older than ours cn=config ours 20140415154713.807278Z#000000#000#000000, new 20140415154704.888204Z#000000#000#000000
and indeed, the seed entries are NOT overwritten I have to "touch" them on the master to force the replication.
so my question is: do I use the -c option correctly, or is there a bug?
thanks for your help. regards,
hello,
FYI, I have filled an ITS #7840
