Setting up FTP service on your filer

Configuring an authentication style

About configuring an authentication style

You can configure one of the following authentication styles for the FTP service on your filer:

UNIX
NTLM
Mixed

By default, the authentication style is set to Mixed when the FTP service is enabled.

For more information about these authentication styles, see Authentication database for the FTP service.

Limitation of NTLM authentication style

Data ONTAP allows only lowercase names for user home directories. Even if you specify the user name in uppercase, you must make sure that a lowercase name is specified for the user's home directory; otherwise, the user will not be able to access files after logging in.

Configuring the UNIX authentication style

To configure the UNIX authentication style for the FTP service on your filer, complete the following step.

Step	Action
1	If...	Then...
	You want to use only the /etc/passwd file for authentication and have NIS disabled on your filer	Enter the following command: options ftpd.auth_style unix
	You want to use only the /etc/passwd file for authentication and have NIS enabled on your filer	Enter the following command: options ftpd.auth_style unix
		In the /etc/nsswitch.conf file, edit the passwd map as follows: passwd: files
	You want to use only NIS for authentication	Enter the following commands: options ftpd.auth_style unix options nis.enable on
	You want to use only NIS for authentication	In the /etc/nsswitch.conf file, edit the passwd map as follows: passwd: nis
	You want to use both /etc/passwd and NIS for authentication	Enter the following commands: options ftpd.auth_style unix options nis.enable on
	You want to use both /etc/passwd and NIS for authentication	In the /etc/nsswitch.conf file, edit the passwd map as follows: passwd: files nis

Configuring the NTLM authentication style

To configure the NTLM authentication style for the FTP service on your filer, complete the following step.

Step	Action
1	Enter the following command: options ftpd.auth_style ntlm options cifs.home_dir pathname where pathname is location of user home directories; for example, \home. Note The home directory of a user is a combination of pathname specified by the `cifs.home_dir` option and the user ID of the user. The path name specified by the `cifs.home_dir` option is case-sensitive; however, the user ID is not case-sensitive. For example, if `cifs.home_dir` is \home and the user name is JOHN, the home directory for the user is \home\john.

Step

Action

Enter the following command:

options ftpd.auth_style ntlm

options cifs.home_dir pathname

where pathname is location of user home directories; for example, \home.

Note
The home directory of a user is a combination of pathname specified by the cifs.home_dir option and the user ID of the user. The path name specified by the cifs.home_dir option is case-sensitive; however, the user ID is not case-sensitive. For example, if cifs.home_dir is \home and the user name is JOHN, the home directory for the user is \home\john.

Configuring the Mixed authentication style

To configure the Mixed authentication style on your filer, complete the following step.

Note
If you want to use NIS for authentication of users specifying their user name without a domain name, make sure that the nis.enable option on your filer is set to On. For more information, see Authentication database for the FTP service and Configuring the UNIX authentication style.

Step	Action
1	Enter the following command: options ftpd.auth_style mixed
