password file number of entries

1. At the time of creating a password file you specify the maximum number of distinct DBA and OPERs. But say already this step had been taken care and now I want to see in the exsisting password file the max. no of entries specified. Which data dictionary or anyother place where we can get this info. take the size of the password file, subtract 1024 and divide by 128. Eg: $ ls -lag xxx yyy zzz -rwSr----- 1 tkyte other 3584 Dec 27 11:25 xxx -rwSr----- 1 tkyte other 6144 Dec 27 11:25 yyy 3584 -> 2560 -> 20, xxx has 20 entries 6144 -> 5120 -> 40, yyy has 40 entries
