LDAP Synchronization error

henrychoi_yw

Hey guys,
From my last post, I found out my Alfresco does not sync user groups from AD. So I tried to look around and follow the posts, end up broke Alfresco and removed all the users and user groups. So I tried reconfig the whole alfresco-global.properties, this is my properties file:
<blockcode>

And I am getting this errors from the alfresco.log:

I have search around the Internet, some people said it's about LDAP can not connect properly. I tried to use LDAP browser on my Linux server to connect to AD, the authentication works and I can see the users and groups in the list. However, it does not work when I tried to connect from Alfresco.

Just want to know if any one can see what happening to my error log.

Many Thanks
Henry

Are you still having this issue? I've been struggling with LDAP setting as well. In this case, it is the LDAP server that is hanging up on you. Do you know how many groups/users it is trying to synch. There should be a count higher up in the log. Mine was 576/13706… Way to many.

But when I try to limit it to a smaller specific group, it sees 0/0.

We have a set of groups, one for each environment: dev/prod/qa/uat. I want to focus this Alfresco installation to one of those groups. So, I tried the following for group and user base:

ldap.synchronization.groupSearchBase=CN=petcms-dev,OU=petcms,OU=appgroups,OU=accessmgmnt,DC=ers,DC=equifax,DC=com
ldap.synchronization.userSearchBase=OU=useraccounts,OU=accounts,OU=accessmgmnt,DC=ers,DC=equifax,DC=com

This resulted on 0/13706. No groups and the synch of users failed. It appears from the Alfresco documentation, that the value must start with an OU, so I cannot use the individual groups, but I can use the parent:

OU=petcms,OU=appgroups,OU=accessmgmnt,DC=ers,DC=equifax,DC=com

CN=petcms-dev,OU=petcms,OU=appgroups,OU=accessmgmnt,DC=ers,DC=equifax,DC=com
CN=petcms-prod,OU=petcms,OU=appgroups,OU=accessmgmnt,DC=ers,DC=equifax,DC=com
CN=petcms-qa,OU=petcms,OU=appgroups,OU=accessmgmnt,DC=ers,DC=equifax,DC=com
CN=petcms-uat,OU=petcms,OU=appgroups,OU=accessmgmnt,DC=ers,DC=equifax,DC=com

But this defeats the purpose of the groups. From the docs…

ldap.synchronization.groupSearchBase — The Distinguished Name (DN) of the Organizational Unit (OU) below which security groups can be found. You can determine the appropriate DN by browsing to security groups in an LDAP browser.
ldap.synchronization.userSearchBase — The distinguished name (DN) of the Organizational Unit (OU) below which user accounts can be found. You can determine the appropriate DN by browsing to user accounts in an LDAP browser.

Notice the phrase, "The Distinguished Name (DN) of the Organizational Unit (OU) below which…". This does not make sense. I have to specify the parent node, which will pull in all the groups, or all the users? I can't specify a group?

There are 4 groups and 13
