Liferay 6.1 integrate with two ADs through portal-ext.properties

[Abhi R, módosítva 9 év-val korábban]

Hi guys,

I'm trying to integrate my Liferay Environment with two ADs and want to do that through portal-ext.properties. I am successfully able to do it for one AD but when I add details of two ADs I get a null pointer exception in UnsyncStringReader.
02:46:22,648 ERROR [liferay/scheduler_dispatch-2][PortalLDAPImporterImpl:205] Error importing LDAP users and groups

My configurations are as follows. I'd appreciate any pointers towards why this null pointer is occurring!

Hi, looking into code
* https://github.com/liferay/liferay-portal/blob/6.1.1-ga2/portal-service/src/com/liferay/portal/kernel/util/PropertiesUtil.java#L208
* https://github.com/liferay/liferay-portal/blob/6.1.1-ga2/portal-impl/src/com/liferay/portal/security/ldap/LDAPSettingsUtil.java#L102

you need to create also these properties:

ldap.group.mappings.0=
ldap.group.mappings.1=

Hi Tomas,

Thanks for your quick reply.

I don't want to import any groups, just users from specific Organizational Units in from two different ADs?
Do I have to set this property and import Group when I don't need them. Is there a workaround?

Thanks,
Abhi.

Hi Abhi,

you need the properties, but they can hold no value.

I didn't try it but try this: ldap.import.group.search.filter.enabled=false
