OpenKM.xml

  • Important login (ldap://192.168.0.13:389/dc=some,dc=com) sets default filter base queries at dc=some,dc=com with is concatenated by default in all filter queries .
  • Roles ( groups ) filter base is ou=roles ( real distinguised name is ou=roles,dc=some,dc=com ). Any valid roles should have it as parent. <beans:constructor-arg value="ou=roles"/> really points to <beans:constructor-arg value="ou=roles,dc=some,dc=com"/>
  • Users filter base is ou=organization ( real distinguised name is ou=organization,dc=some,dc=com ). Any valid user should have it as parent. <beans:constructor-arg index="0" value="ou=organization" /> to <beans:constructor-arg index="0" value="ou=organization,dc=some,dc=com" />
  • User filter is uid={0}
  • Finally take in consideration the value 1 at <beans:property name="groupSearchFilter" value="memberUid={1}"/>
