Change max results in UI

This option limits the search results in UI. 

max.search.results=25

Change principal adapter

OpenKM can handle user access using the JBoss DatabasePrincipalAdapter login module by default. OpenKM needs an available method for reading users and roles. The class DatabasePrincipalAdapter does this job. For more information take a look at OpenKM authentication and Active Directory 

principal.adapter=com.openkm.core.DatabasePrincipalAdapter

Switch OpenKM to demo mode

In demo mode some options are disabled by default. 

system.demo=on

Enabling OCR

To enable OCR you must put the files system path of OCR engine 

system.ocr=/usr/local/bin/tesseract

Setting default lang to OpenKM UI

OpenKM By default tries setting language depending end user language browser. But you can set a language for all OpenKM users by default 

default.lang=es-ES

Force username to lowercase

You can forge all username be written in lower case. It's useful for example when you integrate with microsoft active directory where username is not case sensitive 

system.login.username.lowercase=on

notify.message.body=Document: <a href=\"{0}\">{1}</a>

Configuring password validation

To configuring password validation you have several properties. CompletePasswordValidator is default password validator class that comes by default with OpenKM. By default validator is not enabled. You can also create your own Create password validator Padlock.gif.

You can select which rules validation you want to enable, for example if you only enable validator.password.min.length property, the validator only will validate minimal length. 

validator.password=com.openkm.validator.password.CompletePasswordValidator
validator.password.min.length=numeric value greater than 0
validator.password.max.length=numeric value greater than 0
validator.password.min.lowercase=numeric value greater than 0
validator.password.min.uppercase=numeric value greater than 0
validator.password.min.digits=numeric value greater than 0
validator.password.mini.special=numeric value greater than 0
validator.password.error.min.length=Your message error
validator.password.error.max.length=Your message error
validator.password.error.min.lowercase=Your message error
validator.password.error.max.uppercase=Your message error
validator.password.error.min.digits=Your message error
validator.password.error.min.special=Your message error

Configuring chat service

By default chat and autologin are enabled. In order to enable or disable values can be "on" or "off". 

chat.enabled=off
chat.autologin=off

Configuring schedulers

There're some schedulers that OpenKM uses. Some internally like mail importer and getting repository news and others used by user interface like dashboard refreshing time and keepalive.


Values must be in minutes.


OpenKM inquires for repository news ( be default one time at day ) 

schedule.repository.info=240

OpenKM imports mails from imap server ( by default each 60 minutes ) 

schedule.mail.importer=60

KeepAlive is used by user interface to mantaining browser connected to OpenKM althought users stay sometime without using any operation. For it reason never might be lower that server timeout session ( by default it's 30 minutes ). 

schedule.session.keepalive=15

Dashboard data is refreshing by default each 30 minutes. 

schedule.dashboard.refresh=30
