Testing Publishing Queue

Install external directory on separate system or VM and emulate network congestion by use the following command:

$ tc qdisc add dev eth0 root netem delay 4000ms 1000ms 25%

This causes the added delay to be 4000ms ± 1000ms with the next random element depending 25% on the last one.

Multiple Certificates Issued from Single Request

  • Enable LDAP publishing to external directory with configured delay.

  • Submit certificate request, which has to be approved by CA agent.

  • Open two agent pages with submitted certificate request.

  • Approve above certificate request simultaneously through both pages.

Publishing Queue

  • Enable LDAP publishing to external directory with configured delay.

  • Create LDAP entry for UID=qqq,OU=People,DC=example,DC=com

dn: uid=qqq,ou=People,dc=example,dc=com
changetype: add
objectClass: top
objectClass: person
objectClass: organizationalPerson
objectClass: inetorgperson
uid: qqq
cn: qq qq
sn: qq
givenName: qq

Publishing Queue Paging

  • Decrease page size to 9 and restart CA:

ca.publish.queue.enable=true
ca.publish.queue.maxNumberOfThreads=3
ca.publish.queue.priorityLevel=0
ca.publish.queue.pageSize=9

  • Follow the steps for Publishing Queue till the moment in which paging mechanism can be verified.

Future Improvements

Submitting request can be automated. This automation should improve speed in which this feature can be tested.
