Open Ldap for alfresco3.4

[gowri_7489]

Hi,

      Im using alfresco3.4 community.can any one help me to integrate OpenLdap with alfresco3.4 community edition.
And tell me where to download it.

On a Linux server you can use a tool like apt to install OpenLDAP. You'll want slapd and ldap-utils, so the command would be:
apt-get install slapd ldap-utils

Google can offer more help on install and config of OpenLDAP.

For help configuring OpenLDAP with Alfresco, see the official documentation:
http://docs.alfresco.com/4.0/topic/com.alfresco.enterprise.doc/concepts/auth-config-examples.html
http://docs.alfresco.com/4.0/topic/com.alfresco.enterprise.doc/concepts/auth-ldap-openldaptips.html

Im using windows and alfresco3.4.I also download OpenLDAP s/w.Now how can i integrate those things?and also my requirement is to login alfresco with one system,and i get this from another system without using login and password?
help me.

To understand how to use OpenLDAP for authentication, consult the documentation links I provided earlier in the thread.

The second requirement you are asking for sounds like single sign-on (SSO). That is a complex requirement and depends on exactly what systems you have in place. I highly recommend reading the official documentation on SSO options that are available out-of-the-box. If it isn't covered there, check the wiki and the forums. If you can't find a step-by-step specific to the systems you are trying to integrate with SSO, you'll likely have to code it yourself.

Thank you.

i install openldap for windows with my system32bit and

i followed the above link you provided for the integration steps.

i include the files for ldap authentication with the following folder

C:\Alfresco\tomcat\shared\classes\alfresco\extension\subsystem\Authentication\ldap\internalLDAP\ldap-authentication.properties

the code is:

# This flag enables use of this LDAP subsystem for authentication. It may be
# that this subsytem should only be used for synchronization, in which case
# this flag should be set to false.

#    - usually pass through what is entered
#      %s

# be performed to resolve the DN dynamically. This allows directories to be structured and doesn't require the user ID to

in this where to include my company,my url and my other details.i also include chaining details.

After this i login with alfresco4.0 with that login,i dont know where it(openldap) located with alfresco4.0.  is any UI portion is available for openLDAP login or tell me how can i login the user with openLdap?

The file you have provided appears to be the out-of-the-box ldap-authentication.properties. You must edit it to match the settings for your local openldap implementation. Alfresco has to be able to determine the host where openldap is running, how to find your users, how to find your groups, and how to bind to your directory.

For example, if I compare my local test ldap-authentication.properties file with yours, here are the differences:

# The URL to connect to the LDAP server 
ldap.authentication.java.naming.provider.url=ldap://localhost:10389

# The default principal to use (only used for LDAP sync)
ldap.synchronization.java.naming.security.principal=uid=admin,ou=system

# The query to select all objects that represent the groups to import.
ldap.synchronization.groupQuery=(objectclass\=groupOfUniqueNames)

# The query to select objects that represent the groups to import that have changed since a certain time.
ldap.synchronization.groupDifferentialQuery=(&(objectclass\=groupOfUniqueNames)(!(modifyTimestamp<\={0})))

# The group search base restricts the LDAP group query to a sub section of tree on the LDAP server.
ldap.synchronization.groupSearchBase=ou\=groups,dc\=someco,dc\=com

# The user search base restricts the LDAP user query to a sub section of tree on the LDAP server.
ldap.synchronization.userSearchBase=ou\=people,dc\=someco,dc\=com

# The attribute on LDAP group objects to map to the authority display name property in Alfresco
ldap.synchronization.groupDisplayNameAttributeName=cn

# The group type in LDAP
ldap.synchronization.groupType=groupOfUniqueNames

# The attribute in LDAP on group objects that defines the DN for its members
ldap.synchronization.groupMemberAttributeName=uniqueMember‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I'm running Apache Directory Server, not OpenLDAP, so some of these values may be different for you, but at least it gives you an idea of what you must change to make the configuration work for your LDAP setup.

thanks jeff.

         I now have a doubt that after install open ldap i changed some details in slapd.conf file and maxcrc.ldif file.
Then i login using(created in maxcrc.ldif this file)openLDAP userid and password.it provided the remote authentication failed error.how can i use openLDAP?help me?

[jpotts]

I use Apache Directory Server so I can't be of much help here. But many people use OpenLDAP and it isn't Alfresco-specific, so you might see if some OpenLDAP resources can help you. You might start here:

[gowri_7489]

i need better help.because still i cant connect alfresco4.0 community with openLDAP.

its not sync with alfresco4.0.
