Subject: moved rdn parsing in a dedicated routine, ldap_str2rdn(), that can be used directly... 
X-Git-Tag: LDBM_PRE_GIANT_RWLOCK~914
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=a2eec74fc1d535fa9092f4d7b82a669b39eef539;p=openldap

moved rdn parsing in a dedicated routine, ldap_str2rdn(), that can be used directly; now ldap_rdn2str() handles all the formats
