Passcore API returns IncorrectCredentials insted of ComplexPassword error response

[drbogar]

PassCore Server

• OS: Linux/Docker
• Provider: Active Directory
• Log (without sensitive information):

warn: PassCoreLDAPProvider[0]
      Resolved Win32 API Error: code=1325 name=ERROR_PASSWORD_RESTRICTION desc=Unable to update the password. The value provided for the new password does not meet the length, complexity, or history requirements of the domain. - LdapException: Constraint Violation (19) Constraint Violation
      LdapException: Server Message: 0000052D: AtrErr: DSID-031910B8, #1:
        0: 0000052D: DSID-031910B8, problem 1005 (CONSTRAINT_ATT_TYPE), data 0, Att 9005a (unicodePwd)

      LdapException: Matched DN:

Describe the bug
If the new password does not meet the Active Directory requirements, the logs will show the real error, but the web interface will say that I have entered the current password incorrectly.

I think the problem is that all returned errors from the provider are translated to invalidCredentials:
https://github.com/unosquare/passcore/blob/master/src/Zyborg.PassCore.PasswordProvider.LDAP/LdapPasswordChangeProvider.cs#L195

Expected behavior
I think that the passcore API should return ApiErrorCode.ComplexPassword instead of ApiErrorCode.IncorrectCredentials, if that's the response it gets from the provider.

Same error (on my machine) with the log entry Unable to find username: [foobar]. The frontend shows You need to provide the correct current password..

If I am allowed use your issue.

Of course you can use my issue. If I understand correctly, this is the same error.
