One is 7 char, second is 12 char long. They both work for the same account.

anything after first 8 is ignored for systems using DES.

Thanks, Frank, thanks all
Still I don't understand why those 2 different passwords work for me, they have different chars/order . Can anybody can explain this for me or send to any info.
I just checked they have diff md5 value, even for first 7 and 8 chars. Those are completely diff combinations.

Gracias

I have never used RHEL and seldom use Linux, but my first guess would be that your system is using PAM and that it's configured to allow multiple forms of authentication. Perhaps the contents of /etc/pam.d/login (if it exists on your system) might shed some light.

what is the output after execute the below command?

Code:

$ cat /etc/pam.d/system-auth /etc/nsswitch.conf

Just a suggestion:

The hashing algorithm (at least the original one mentioned by Corona and some others used - don't know which exactly you are employing here) was a surjective function. This means that every password has one and only one hash value, but not every hash value has exactly one password. Several passwords can have the same hash value.

This might be the case here.

I hope this helps.
