Hi,

I've installed the 5.1.7 version on Linux box and configured it with AD for authentication but after login it hangs at the splash screen and gives this error "Error communicating with the server (getUserWorkspace)"

below is the error from the log file:

The source line is:
Code: Select all
workspace.setRoleList(OKMAuth.getInstance().getRolesByUser(null, user.getId()));
I think the "user" variable maybe null. This can be because the principal adapter is not well configured. BTW, in OpenKM 5.1.x the OpenKM.cfg configuration file is only used for hibernate.* properties. The others are managed from Administration and stored in database.

So shall I change it back to local authentication and use the administration tab to configure the authentication ?

Or connect to the database and make the changes into the OKM_CONFIG table.

Remember after first startup all properties are stored in DBMS, and changes on OpenKM.cfg will not take any effect ( into OpenKM.cfg will only have sense leave the DBMS properties others can be deleted after first startup and must be changed on administration tab ).

Hi,

I've rest everything back to normal authentication and logged in as okmAdmin and entered all the configuration on the administration tab and changed the login-config.xml, then if I change the hibernate.hbm2ddl to none and restart the service I get a lot of "Table not found in statement" errors and if i leave hibernate.hbm2ddl to create I get the old error I posted earlier.

Appreciate your help.

Thanks & regards,
Sagar

Do you got information on that OpenKM installation ?

Maybe I didn't understand your question; but if you're asking if I have information on the installation, yes I was reading the documentation site.

Thanks & regards,

Properties hibernate.hbm2ddl and hibernate.dialect are configured in the OpenKM.cfg file, isn't it? Can you post your OpenKM.cfg file and a screenshot of the Administration > Configuration?

Also would be nice the OpenKM related part of the login-config.xml from JBoss configuration.

Hi all,

I have reviewed the configuration and got it working, but it is not getting the right role from the AD (AdminRole or UserRole) it always use the default role from the login-config.xml

The other question is that the departments are represented as OUes in the AD and I want to use this to group the users so they can share documents through the group.

Thanks & regards,
Sagar

In OpenKM 5.1.x only these lines are meaninful at OpenKM.cfg:
Code: Select all
hibernate.dialect=org.hibernate.dialect.HSQLDialect
hibernate.hbm2ddl=none
The others are pretty ignored.

I have updated the wiki with a new entry at http://wiki.openkm.com/index.php/Testin ... figuration. This explain a bit better how to configure the LDAP integration.

Comments are welcomed.

Hi,

I tried to use the tool you developed here http://wiki.openkm.com/index.php/Testin ... figuration but the zip file require a password which was not given.

Thanks & regards,
Sagar

It think you're wrong, the http://www.openkm.com/download/OpenKM-5.1-LDAP.zip has not password ( I tested ).

Hi,

Strange I've tried to download it many times and tried to open it with 7zip and winrar but it always asks for the password!

Thanks & regards,
Sagar
