The documents indicate that you can only have one Structural ObjectClass and multiple Aux. ObjectClasses, and I'm a bit hazy on the rules for Abstract ObjectClasses. <o:p></o:p></p><p>If I take the example of needing to add the "host" attribute to a user object. A RHN knowledgebase article indicates to add the "hostobject" ObjectClass rather than the "Account" ObjectClass. My assumption was that "hostobject" was an Aux. ObjectClass, and that "Account" was Structural, but when I look at the two ObjectClasses via the administrative GUI, they both have "Top" listed as the parent ObjectClass. So I'm not certain why one is appropriate and the other is not.<o:p></o:p></p><p>Moving forward I want to be able to combine ObjectClasses to extend available objects without introducing data integrity issues in my ldap directory. I am looking for some clarification of rules regarding structural objectclasses, and if there is an easy way via the admin gui to tell the difference between structural, auxillary, and abstract objectclasses. Also will the directory do some sort of intregrity checking if you attempt to combine improper objectclasses either via commandline or the admin gui?<o:p></o:p></p><p> <o:p></o:p></p><p>Thanks<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><b><span style='font-size:12.0pt;font-family:"Book Antiqua","serif";color:gray'> Cary Anderson</span></b><span style='font-size:12.0pt;font-family:"Times New Roman","serif";color:#1F497D'><o:p></o:p></span></p><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Arial","sans-serif";color:#1F497D'> </span></b><span style='font-size:12.0pt;font-family:"Times New Roman","serif";color:#1F497D'>916.464.5108<o:p></o:p></span></p><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Arial","sans-serif";color:#333399'>Linux Support</span></b><b><span style='font-size:10.0pt;font-family:"Arial","sans-serif";color:#1F497D'> |</span></b><b><span style='font-size:12.0pt;font-family:"Times New Roman","serif";color:#1F497D'> </span></b><b><span style='font-size:10.0pt;font-family:"Arial","sans-serif";color:maroon'>Engineering Dept</span></b><b><span style='font-size:10.0pt;font-family:"Arial","sans-serif";color:#1F497D'>.</span></b><span style='font-size:12.0pt;font-family:"Times New Roman","serif";color:#1F497D'><o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
