Is there Linked Attributes configuration and usage documentation available?

[Sean Brady]

Hello All,

I have 389 up and running, and had some questions on Linked Attributes.  I found this http://directory.fedoraproject.org/wiki/Linked_Attributes_Design but that is the extent of the documentation that I have found.  Does anyone know of any additional documentation that you can point me to?

I am unclear on exactly how to configure Linked Attributes properly, and how to use them.  Specifically, which ldif file would I need to modify to create a linked attribute?  Would that be dse.ldif, or one of the ldif's in the schema sub-folder (/etc/dirsrv/slapd-<instance_name>/schema)?  What else would I need to know to configure a linked attribute?  What do I need to know about it's usage?

Once I have the details I can post some documentation back to the community- there is nothing in the RedHat Directory Server on this plugin as of yet that I have seen.  I don't think that this can be done through the GUI at this time...

Thanks in advance for the community's help.

OK, I see some helpful errors in the logs here:

linkedattrs-plugin - linked_attrs_parse_config_entry: The linkType config setting is required for linked attribute pair "cn=manager link,cn=linked attributes,cn=plugins,cn=config".

[02/Dec/2009:06:19:24 -0700] linkedattrs-plugin - linked_attrs_parse_config_entry: Invalid config entry [cn=manager link,cn=linked attributes,cn=plugins,cn=config] skipped

So... I am assuming that there is a configuration entry that I need called "linkType", which isn't listed in the link per se, although there is a reference to it in passing.  Can someone help me with the expected type of value, ie is this an attribute type, etc?  What do I need here?

The following was added to my dse.ldif:

dn: cn=Manager Link, cn=Linked Attributes,cn=plugins,cn=config
objectClass: extensibleObject
objectClass: top
cn: Manager Link
linkattribute: directReport
managedattribute: linkmanager

Both the linkattribute "directReport" and managedattribute "linkmanager" are custom attributes added as "MAY" to a custom "employee" objectclass, to which 3 test users have as an attribute value.  I didn't want to conflict with any existing attributes, and I noticed that the directreport attribute did not exist.

Any help is appreciated.

Thanks,
SB

The feature design page you referenced had the configuration attributes 
named incorrectly (the attribute names changed between the design and 
implementation of the feature).  I have updated the configuration 
section of that page to be correct.  Please look here for details:

http://directory.fedoraproject.org/wiki/Linked_Attributes_Design#Configurati...

In short, you need to use "linkType" and "managedType" instead of 
"linkAttribute" and "managedAttribute" in your config entry that you 
have referenced below.
