Subject: Provide (and use) #define shortcuts
X-Git-Tag: OPENLDAP_REL_ENG_2_BP~492
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=a97e3e94e665df092cc512cd5a3f9c5ceac820ef;p=openldap

Provide (and use) #define shortcuts
Really kill global_oc & global_at
Publish schema through LDAP (really, it's there at last :-)
