Server rejects password or password phrase

The z/OS FTP server supports case-sensitive passwords when your RACF® administrator has enabled mixed-case passwords. Verify that you have entered the password correctly, and in the correct case. Password phrases used to log in to a z/OS® FTP server are always case-sensitive.

If you are using a NETRC file or data set to provide the FTP login password, verify that the password is coded correctly and in the correct case.

If the z/OS FTP server rejects a mixed-case or lower-case password that it formerly accepted, it is possible your RACF administrator has disabled RACF mixed-case password support. In that case, it is not possible to log in with any ID whose password has been set to mixed or lower case. Ask your RACF administrator to reset the password.

If the server rejects a password of more than one token, verify that you enclosed the password phrase with quotation marks when you entered it, or when you coded it in the NETRC file or data set.

FTP clients send passwords to the FTP server as ASCII-encoded data. The server must translate the password or password phrase to its native EBCDIC code page because passwords and password phrases are defined to your z/OS security product as EBCDIC strings. If any character of the password phrase does not translate into the correct character, the password will not match the password assigned to the user ID, and logging in will fail. A character might not translate correctly for the following reasons:

The client and server are using different ASCII code pages for the control connection. Verify that the client and server are using the same code page for the control connection.
The client is EBCDIC-based and is using a different EBCDIC code page than the server. Verify that the client and server are using the same native code page.
The client and server are using matching code pages, but one or more characters in the password phrase does not translate into the correct character. Verify that each character assigned to the password phrase can be translated from EBCDIC to ASCII, and from ASCII back to the original EBCDIC character.
