# Script to check LDAP syncrepl replication state between two servers.
|
||||||
|
# One server is consider as provider and the other as consumer.
|
||||||
|
#
|
||||||
|
# This script can check replication state with two method :
|
||||||
|
# - by the fisrt, entryCSN of all entries of LDAP directory will be
|
||||||
|
# compare between two servers
|
||||||
|
# - by the second, all values of all atributes of all entries will
|
||||||
|
# be compare between two servers.
|
||||||
|
# In all case, contextCSN of servers will be compare and entries not
|
||||||
|
# present in consumer or in provider will be notice.
|
||||||
|
#
|
||||||
|
# This script could be use as Nagios plugin (-n argument)
|
||||||
|
#
|
||||||
|
# Requirement :
|
||||||
|
# A single couple of DN and password able to connect to both server
|
||||||
|
# and without restriction to retrieve objects from servers.
