Comment # 2 on bug 1194534 from William Brown

leap153:/ # rpm -ql sudo
/etc/openldap/schema
/etc/openldap/schema/sudo.schema

It looks like this comes from the sudo package itself, not openldap, so it
should probably be directed to them to see if they want to take this on.

However, it's worth noting:

https://doc.opensuse.org/documentation/leap/security/html/book-security/cha-security-ldap.html

"OpenLDAP is deprecated and no longer supported as of SUSE Linux Enterprise 
15.3, replaced by 389 Directory Server. "

Since the openldap packages in leap, and the related ldap integrations for leap
are derived from sle, there is unlikely to be motivation for us to include this
openldap sudo ldif schema. 

In leap and sle I would advise consider migration to 389-ds, or alternately you
could use https://build.opensuse.org/package/show/network:ldap/openldap2
(zypper ar -f obs://network:ldap network:ldap)  and request the schemas from
the upstream openldap maintainer (which is separately managed to openldap in
sle/leap).
