Your application has to deal with it
(and with more weird alias issues).

No, it isn't.

Attribute type descriptions should be handled case-insensitive.

It can handle this automagically if you use ldap.cidict for the entry
dictionaries passed to ldap.modlist.modifyModlist().

python-ldap mainly provides ldap.cidict which a dictionary class with
case-insensitive strings as keys.

Another more sophisticated solution is undocumented class
ldap.schema.models.Entry. But have to implement full schema support for
making real use of it.

Ciao, Michael.
