# This script tests a configuration scenario as described in these URLs:
#
# http://www.openldap.org/lists/openldap-devel/200806/msg00041.html
# http://www.openldap.org/lists/openldap-devel/200806/msg00054.html
#
# Search for "TEST:" to find each major test this script performs.

# The configuration here consist of 3 "sites", each with a "master" and
# a "search" server. One of the sites is the "central", the other two
# are called "site1" and "site2".

# The following notations are used in variable names below to identify
# these servers, the first number defines the $URL# and $PORT# variable
# that server uses:
#
# 1: SMC_*	Site Master Central
# 2: SM1_*	Site Master 1
# 3: SM2_*	Site Master 2
# 4: SSC_*	Search Site Central
# 5: SS1_*	Search Site 1
# 6: SS2_*	Search Site 2

# The master servers all have a set of subordinate databases glued below
# the same suffix database.  Each of the masters are the master for at
# least one of these subordinate databases, but there are never more
# than one master for any single database.  I.e, this is neither a
# traditional single-master configuration, nor what most people think
# of as multi-master, but more what can be called multiple masters.

# The central master replicates to the two other masters, and receives
# updates from them of the backends they are the master for.  There is
# no direct connection between the other two master servers.  All of the
# masters have the syncprov overlay configured on the glue database.

# The search servers replicates from the master server at their site.
# They all have a single database with the glue suffix, but their
# database configuration doesn't matter much in this test.  (This
# database layout was originally created before gluing was introduced
# in OpenLDAP, which is why the search servers doesn't use it).

# The primary objective for gluing the backend databases is not to make
# them look like one huge database but to create a common search suffix
# for the clients.  Searching is mostly done on the search servers, only
# updates are done on the masters.

# It varies which backends that are replicated to which server (hence
# the name asymmetric in this test).  Access control rules on the
# masters are used to control what their consumers receives.  The table
# below gives an overview of which backend (the columns) that are
# replicated to which server (the rows).  A "M" defines the master for
# the backend, a "S" is a slave, and "-" means it is not replicated
# there.  Oh, the table probably looks wrong without the 4-position
# tab-stops OpenLDAP uses...

#		glue	ou1		ou2		sm1ou1	sm1ou2	sm2ou1	sm2ou2
# smc	M		M		M		S		S		S		-
# sm1	S		S		-		M		M		-		-
# sm2	S		S		S		S		-		M		M
# ssc	S		S		-		-		S		-		-
# ss1	S		S		-		S		S		-		-
# ss2	S		S		S		-		-		S		S

# On the central master syncrepl is configured on the subordinate
# databases, as it varies which backends that exists on its providers.
# Had it been used on the glue database then syncrepl would have removed
# the backends replicated from site1 but not present on site2 when it
# synchronizes with site2 (and vice versa).
#
# All the other servers uses syncrepl on the glue database, since
# replicating more than one subordinate database from the same master
# creates (as of the writing of this test script) race conditions that
# causes the replication to fail, as the race tests at the end shows.

# The databases controlled by syncrepl all have $UPDATEDN as their
# RootDN, while the master servers has other RootDN values for the
# backends they are the backend for them self.  This violates the current
# guidelines for gluing databases, which states that the same rootdn
# should be used on all of them.  Unfortunately, this cannot be done on
# site masters 1 and 2.  The backends they manage locally are either not
# present on the central master, or when so they are not replicated back
# to their source, which causes syncrepl to try to remove the content of
# these backends when it synchronizes with the central master.  The
# differing rootdn values used on the backends controlled by syncrepl
# and those managed locally prevents it from succeeding in this.  As
# noted above, moving syncrepl to the subordinate databases is currently
# not an option since that creates race conditions.

# The binddn values used in the syncrepl configurations are chosen to
# make the configuration and access control rules easiest to set up.  It
# occasionally uses a DN that is also used as a RootDN.  This is not a
# good practice and should not be taken as an example for real
# configurations!

# This script will print the content of any invalid contextCSN values it
# detects if the environment variable CSN_VERBOSE is non-empty.  The
# environment variable RACE_TESTS can be set to the number of race test
# iterations the script should perform.

# TEST:
# Run race tests when more than one backend is replicated from the same
# provider.  This will usually fail long before 100 iterations unless
# syncrepl stores the contextCSN in the suffix of its own database, and
# that syncprov follows these rules before updating its own CSN when it
# detects updates from syncrepl:
# 1) A contextCSN value must have been stored in the suffix of all the
#	 syncrepl configured databases within the glued syncprov database.
# 2) Of all contextCSN values stored by syncrepl with the same SID,
#	 syncprov must always select the one with the lowest csn value.
