Liferay and Alfresco Doclib integration

Alfresco uses org.springframework.extensions.webscripts.connector.HttpConnector to talk with
Alfresco. This has the hardcoded value
headers.put("X-Alfresco-Remote-User", user);

Since it is hardcoded,if we change the value of th eheader then the authentication will not be respected.

So change the code to fir the your custom external key CTUSER defined in your external file.






alfresco-noauth
Alfresco - unauthenticated access
Access to Alfresco Repository WebScripts that do not require authentication

alfresco-feed
Alfresco Feed
Alfresco Feed - supports basic HTTP authentication

alfrescoCookie
Alfresco Connector
Connects to an Alfresco instance using cookie-based authentication

ldap sync in Alfresco

org.alfresco.repo.security.sync.UserRegistrySynchronizerJob







${synchronization.import.cron}








From here it calls




ChainingUserRegistrySynchronizer.java has a method by name


syncWithPlugin

private void syncWithPlugin(final String zone, UserRegistry userRegistry, boolean forceUpdate,
boolean allowDeletions, boolean splitTxns, final Set visitedZoneIds, final Set allZoneIds)



It has

final BatchProcessor personProcessor = new BatchProcessor(zone
+ " User Creation and Association", this.transactionService.getRetryingTransactionHelper(),
userRegistry.getPersons(lastModified), this.workerThreads, 10, this.applicationEventPublisher,

userRegistry.getPersons(lastModified)


It calls LDAPUSerRegistry

/*
* (non-Javadoc)
* @see org.alfresco.repo.security.sync.UserRegistry#getPersons(java.util.Date)
*/
public Collection getPersons(Date modifiedSince)
{
return new PersonCollection(modifiedSince);
}


which in turn calls PersonCollection. The PersonCollection has the constructor to initialize the query


PersonIterator has the next to get the users from the system

private NodeDescription fetchNext() throws NamingException
{
boolean readyForNextPage;
do
{
readyForNextPage = this.searchResults == null;
while (!readyForNextPage && this.searchResults.hasMore())
{
SearchResult result = this.searchResults.next();
Attributes attributes = result.getAttributes();
Attribute uidAttribute = attributes.get(LDAPUserRegistry.this.userIdAttributeName);
if (uidAttribute == null)
{
if (LDAPUserRegistry.this.errorOnMissingUID)
{
throw new AlfrescoRuntimeException(
"User returned by user search does not have mandatory user id attribute "
+ attributes);
}
else
{
LDAPUserRegistry.logger
.warn("User returned by user search does not have mandatory user id attribute "
+ attributes);
continue;
}
}
String uid = (String) uidAttribute.get(0);

if (this.uids.contains(uid))
{
LDAPUserRegistry.logger
.warn("Duplicate uid found - there will be more than one person object for this user - "
+ uid);
}

this.uids.add(uid);

if (LDAPUserRegistry.logger.isDebugEnabled())
{
LDAPUserRegistry.logger.debug("Adding user for " + uid);
}

// Apply the mapped properties to the node description
return mapToNode(LDAPUserRegistry.this.personAttributeMapping,
LDAPUserRegistry.this.personAttributeDefaults, result);
}

// Examine the paged results control response for an indication that another page is available
if (!readyForNextPage)
{
readyForNextPage = LDAPUserRegistry.this.ldapInitialContextFactory.hasNextPage(this.ctx,
LDAPUserRegistry.this.queryBatchSize);
}

// Fetch the next page if there is one
if (readyForNextPage)
{
this.searchResults = this.ctx.search(LDAPUserRegistry.this.userSearchBase,
PersonCollection.this.query, this.userSearchCtls);
}
}
while (readyForNextPage);
this.searchResults.close();
this.searchResults = null;
this.ctx.close();
this.ctx = null;
return null;
}
