LUCAT is the university common directory service. In LUCAT, information about all employees and students is stored. LUCAT is a so-called LDAP directory service, where the information is grouped in a tree structure.

The responsibility for updating the information in LUCAT is distributed. This means that in every organization or department within the university, it is decided that there should be a LUCAT Manager (directory administrator), which is responsible for ensuring that the information about the employees is current.


In connection with LUCAT, there is also linked a special login with a username and password for each employee and student. You should have received your LUCAT login information when you joined the university for the first time as an employee. These credentials are used extensively for logging into many administrative systems, so take good care of the details and keep them secret.

For the employees of the LTH Faculty Office, the LUCAT username in most cases begins with the prefix kans- and for the employees of EIT the usernames often begin with the prefix eit-. Other units have other prefixes.

If you have previously worked elsewhere at the university, however, you keep your previous username and your previous login credentials. Usernames in LUCAT never change. However, information about where you are employed is updated.

You can change the LUCAT password and some other information in LUCAT yourself, whenever you want. See below under “More Information”.

Your password is a valuable credential, and you should protect it carefully. You should never enter your password on a web page that you do not trust! When you visit the above web page, please therefore check two things:

  1. The domain of the URL should end in “”.
  2. The page should be protected by a padlock, and when you click on the padlock, information about that page should be identified with the same domain as the URL, with “” at the end.

If these two things are met, there is good reason to believe that the page belongs to the university, and that it can be trusted and is safe enough for you to enter your password on it.
