title: Debug ldapmodify schema addition
body: <p>I am attempting to add an <code>objectGUID</code> attribute to an existing LDAP database. I apply the following ldifs:</p>
  <pre><code>dn: cn={3}inetorgperson,cn=schema,cn=config
  changetype: modify
  add: olcAttributeTypes
  olcAttributeTypes: ( 1.3.6.1.4.1.1234.1.34234234
    NAME 'objectGUID'
    DESC 'text here'
    SYNTAX 1.3.6.1.4.1.1466.115.121.1.44 )
  </code></pre>
  <p>and:</p>
  <pre><code>dn: cn={3}inetorgperson,cn=schema,cn=config
  changetype: modify
  delete: olcObjectClasses
  olcObjectClasses: {0}( 2.16.840.1.113730.3.2.2 NAME 'inetOrgPerson' DESC 'RF
   C2798: Internet Organizational Person' SUP organizationalPerson STRUCTURAL
   MAY ( audio $ businessCategory $ carLicense $ departmentNumber $ displayNam
   e $ employeeNumber $ employeeType $ givenName $ homePhone $ homePostalAddre
   ss $ initials $ jpegPhoto $ labeledURI $ mail $ manager $ mobile $ o $ page
   r $ photo $ roomNumber $ secretary $ uid $ userCertificate $ x500uniqueIden
   tifier $ preferredLanguage $ userSMIMECertificate $ userPKCS12 ) )

  <p>Both seem to apply successfully. From phpLDAPAdmin, I cannot see the changes. I am using an openLDAP server. Is there some LDAP technique that I might be missing? Sorry for the basic question, a bit of an LDAP beginner here...</p>
