Problem: On unsuccessful login attempts via rexec/rexecd the bad login counter (u_numunsuclog) is updated as it should, however on any successful login the bad login counter does not get cleared. So if users inadvertently miss type their password even once between successful logins they will eventually be locked out. Lockouts should only occur when consecutive unsuccessful logins exceed the allowed bad logins. Note: For those of you how have converted to a trusted system and have not applied patch PHNE_12161 you are vulnerable to a brut force attack of guessing password via rexec. Patch PHNE_12161 fix a problem of not updating the bad login counter (u_numunsuclog) circumvent the lockout feature of unsuccessful user logins. This problem has been report to HP and is currently being addressed. -- (...Later..:) :)**************************(: Exxon Research & Engineering (: _/_/_/ _/_/ _/_/_/:) Kevin K.
