Renaming extensionAttribute1 concerns

Hello

I would like to renmae my extension attribute 1 to 'hours of operation' for means of storing that in AD without extending the schema.  I am looking to change the lDAPDisplayName attribute As I understand it this is done in ADSI edit.

I hear this will cause a problem if we ever add another domain controller and run /domainprep.  Is this true?  and if it is, at the time a future DC is added can i temporarily rename that attribute back to its default then add the DC and rename it back to 'hours of operation'?

much thanks
Eric

These are custom Attributes. They should not have any affect.  I used ADMODIFY to change it and apply my Recipient Policies

As a rule I would caution against renaming an attribute within the Schema, since Active Directory or another application such as Exchange may have a dependency on it - i.e., there may be a code branch in Exchange that looks for an attribute named "extensionAttribute1", and if it can't find it you will receive an error of some level of severity or another.

If you want to use one of these attributes to hold your hours of operation data, that's generally fine, but actually renaming the attribute is something that I would avoid.

Hope this helps.

One for and one against.

Anyone else know if this will negativly impact future /domainprep ?

I never changed the actual extensionAttributeX.  I changed the Value.
