This article was previously published under Q306026



SYMPTOMS
Changing a password for a user account for a Services for UNIX (SFU) user may cause CPU usage for the Local Security Authority Server service (LSASS) to go to 98 percent for some time. You can see the CPU usage for this process on the Processes tab in Windows Task Manager.



CAUSE
This issue occurs because the Network Information service (NIS) process (Nissvc.exe) makes many Lightweight Directory Access Protocol (LDAP) requests to rebuild the UNIX files in the following folder:

%Homedrive%\SFU\Nis\MapCache\
