Thank you for raising this issue. While we can see how this feature would be useful, we have no plans to implement it in the foreseeable future. In order to set expectations, we're closing this request now.

Thanks again for your idea.

Yes, we'll have to wait.

seems to be still unresolved in the actual Confluence 5.x Release

Does anyone know if this is still unresolved?

what about that ? We still have the problem, Multivalue Entries from external Userdatabases in Confluence are still not supportet, applications like the SAP NetWeaver Portal are able to handle Multi Value Fields.
It's an important feature for huge companys where Persons with equal names are common.

of course....(as I mentioned we have more then 20.000 Users , working worldwide, connected in one LDAP)
for a better understanding here is a short cut of a LDAP entry regarding my own data ( I have deleted sensitive infos, btw. set them to xxx.
At the moment we use in confluence user schema settings "Name Attribute" "cn" as well as for RDN. But this is not working due to amount of users with equal entrys. We must not change or set different usernames for "cn" this relates to our system architecture, therefore we have the multivalue field UID - this one is unique filled BUT with multiple Entries - every system is able to deal with this multivalue field but confluence. I my case for example, I should be able to log in either with Dennis Guse or with gd3867x.

uid: Dennis Guse
uid: gd3867x
uid: dennis.guse@xx.xxx

But that still means, that you have to use different usernames for each user.
The point is, that one user can have multiple usernames, but still these usernames point only to one specific user.
It is not possible to have different users with the same name.
For instance:
Users John Doe, Joe Doe and Jonathan Doe are three different users. Typical loginname for users are 2 letters from firstname, all letters from lastname.
Would result in:
jodoe
jndoe
jedoe

Multi-valued uids could be:
jodoe.lotus, jodoe.sap, jodoe
jndoe.lotus, jndoe.sap, jndoe
jedoe.lotus,jedoe.sap, jedoe

The thing is, in a company with multiple systems (SAP Portal, Lotus Notes, Microsoft Sharepoint, JIRA and Confluence) and one LDAP with more than 20K user entrys we experience the issue, that two or three useres (at the moment approx. 30-35 Users) with the same name occure. We have up to 5 comma seperated entrys in the multi user field UID and it would be great if confluence would be able to take all of them, so that users can login with each of them.
