lock wait timeout exceeded when using LDAP user/group import

rcalmbac — Fri, 23 Mar 2007 06:33:47 GMT

I'm using Alfresco 2.0 (alfresco-community-war-2.0.0.tar.gz) on Red Hat Linux with JRE 1.5.0_11, Tomcat 5.5.23, MySQL 5.0.24, and AD as the LDAP server. I have chaining authentication configured and after changing the bean id in chaining-authentication-context.xml from "authenticationServiceImpl" to

Hi

I have not seen any lock issues of this kind with InnoDB.

I think a look at the config is required.

Are you clearing out entries when importing people?
This is bad in general - as you loose personalisation.

This could be the source of the lock.

Regards

Andy

I am not clearing out users but I am clearing out groups. These are the defaults and they seem reasonable. Note that the timeouts happen even if I only enable ldapPeopleTrigger, which does not do any clearing out.

One thing I noticed - and I don't know whether this is at all related to the timeout problem - is that the sample for straight LDAP authentication overrides the default authenticationComponent bean, but the sample for chaining authentication never actually overrides the default authenticationComponent bean, which is referenced in a number of places in the Alfresco configuration. Doesn't that mean that the authentication override is incomplete?

Below are my authentication related configs from $CATALINA_BASE/shared/classes/alfresco/extension.

Re: lock wait timeout exceeded when using LDAP user/group import

Hello,
I have exactly the same issue when trying to import the customer 14000 OpenLDAP users into MySQL.
And group import fails too with Data truncation: Data too long for column 'serializable_value' at row 1

Which logs should I enable to investigate that lock wait timeout ?
