Issue ID: 9797 Summary: userPrincipalName doesn't work with OpenLDAP Product: OpenLDAP Version: 2.6.0 Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: slapd Assignee: bugs@openldap.org Reporter: akshay.polji@gmail.com Target Milestone: ---

Recently I was trying to perform a POC that included the Hashicorp vault. I tried to configure Hashicorp Vault LDAP login using OpenLDAP. However, I failed to do so as the Hashicorp vault was trying to query the OpenLDAP with filter="(?userPrincipalName=test1@example.com)"

I got the query o/p as conn=1146 op=1 SEARCH RESULT tag=101 err=32 nentries=0 text= onn=1146 fd=12 closed (connection lost)

Even though the ldapsearch worked for the same user.

The problem seems to be the fact that OpenLDAP doesn't support "userPrincipalName" as the attribute.

Wanted to understand if 'userPrincipalName' could be added?
