--- Comment #10 from Howard Chu hyc@openldap.org --- (In reply to elecharny from comment #9)
My bad, it was a copy of a slapd.d files, most certainly converted from a slapd.conf, but it was provided as is, I have no idea how the conversion was done. It's very likely the slapd.conf contained both attribute, converted by a slaptest.
No. Internally the flag is only stored once, so even if it appeared twice in slapd.conf the conversion would only emit a single attribute.
Also, slapd would never emit both versions of the attribute name. Older releases only know the old name. Newer releases only use the new name. The only way for both attributes to have gotten into the LDIF is for someone to have manually edited the LDIF and put the 2nd one there. Thus, not our bug.
