回复: replica from slave to master still did't work in 2.0.7 ??
first sorry for my last letter did not say clearly , the slave to master
replica which I point is when I use the client tools to send a update action
to the slave slapd, the slave slapd will send back a updateref to the client
tools to refer the master slapd , and then the client tools send a new
update action to the master slapd, then the master slapd implement the
update action and write a replica log file , which the slurpd daemon read it
and propagate the update data to the slave slapd , then all work is done .
I read the Admin Guide section 3, there have a picture point the action
which I descirbe above , but when I settle my test system , I find that this
can not to implement , indeed I have the follow result :
1. the master to slave replica is work well ;
2. when you use a OpenLDAP client tool to update the slave slapd , if
your bind DN is the same as the updatedn which in the slave slapd conf file,
the slave slapd did not return a referral at all , even if you use the globe
referral directive instead of the updatedn directive .
3. if your bind DN is different from the updatedn in the slave slapd conf
file , then the slave slapd will return a Referral , and when I use the -C
parameter to implement the return referra to the master slapd , there have
"Insufficent Access" display .
4. so I then use the following ACL in the master slapd conf file to test
access to *
by * wirte
5. well, then the update action is done , but when I use ldapsearch to
search the DIT , I find that the master slapd' DIT is update , but the slave
slapd's DIT is not update , then I check the replica directory which to
store the temproary log file , then I find that there have a reject file ,
this point that the master update itself and write the replica log file ,
but the slurpd did not implement the update to the slave slapd .
6. I check the reject file , and find that there have a error , which is
there is not the correct DN , then I changed it by hand, and want to use the
One-Shot mode of slurpd to do the rest work , but when I use the following
command , it did not display any incorrcet , but the work still did not done
slurpd -f /the master slapd conf file -t /the temp directory to store
log file -r /the reject log file -o
MY conclusion :
1. the slave to master update is not work well, this maybe is the
OpenLDAP client tool is not smart enought to implement the updateref .
2. the slurpd's One-Shot mode is also not work well .
thanks for any suggest !!
