LFCS · Question #188
Which one of the following pieces of information is not present in the slurpd replication log file?
The correct answer is D. A timestamp of when the change has taken place on the slave. The slurpd replication log primarily records modifications made on the master server, including their timestamp, the slave's address, and the initiating user. However, it does not record the specific timestamp of when these changes are applied on each individual slave server.
Question
Options
- AA timestamp of when the modification took place.

- CThe name of the user who initiated the modification.

Why each option
The `slurpd` replication log primarily records modifications made on the master server, including their timestamp, the slave's address, and the initiating user. However, it does not record the specific timestamp of when these changes are applied on each individual slave server.
A timestamp of when the modification took place on the master server is a crucial piece of information recorded in the replication log to maintain the order of changes.
The address of the remote LDAP slave server is necessary information for `slurpd` to know where to send updates and is typically logged during the replication process or connection attempts.
The name of the user who initiated the modification (e.g., the DN of the binder) is generally part of the modification record and is included in the replication stream from the master.
The `slurpd` replication log, used for older OpenLDAP versions, logs details about changes occurring on the *master* LDAP server, such as the modification timestamp on the master, the type of operation, and the entry's DN. It does not typically record the precise timestamp indicating when that specific change was successfully applied or took effect on a *slave* server; such events would be logged on the slave itself.
