Description Florian Best

A DN is case insensitive. Various functions in ucsschool-lib can fail.

For example:
486 »   def isStudent(self, userDN):
487 »   »   return userDN.endswith(self.students)

No. this is generally not true:
A DN is a sequence of RDNs. An RDN is a sequence of Attribute-value 
pairs. Each attribute has its own schema definition with its own 
governing rules. Some attributes are case-sensitive, some are not. As 
such, a complete DN may have components that are case-sensitive as well 
as case-insensitive.

We should use the new univention.uldap.access.compare_dn() function instead.

This issue has been filed against UCS 4.4.

UCS 4.4 is out of maintenance and UCS components may have vastly changed in later releases. Thus, this issue is now being closed.

If this issue still occurs in newer UCS versions, please use "Clone this bug" or reopen this issue. In this case please provide detailed information on how this issue is affecting you.
