NTLM failed redirecting to Login Page

NTLM failed redirecting to Login Page

Hello to all,
 
we have experienced the "NTLM failed redirecting to login page" problem in one of our technicians after he added a field in "Search Requester" view. After some tests, we think that is a problem of technician profile.
 

 
In SSO log you can see this message (we have removed the names of technicians):
 

 
Could you tell us if there is any solution?
 
Thanks in advance
