The UserAgent was:

Mozilla/4.0 (compatible; MSIE 7.0; TOB 6.05; Windows NT 6.0; Trident/4.0; 
GTB6; SLCC1; .NET CLR 2.0.50727; Media Center PC 5.0; .NET CLR 1.1.4322; 
.NET CLR 3.5.30729; .NET CLR 3.0.30729; AskTB5.4)

I correlated "Successful logins" with nsession as session id
in the catalog log file with Apache access log entries.

Adding the NotRobotUA directive fixed the problem.
