By default, the passwd command assumes a minimum length of six characters. You can use the PASSLENGTH default in the /etc/defaults/passwd files to change that by setting the minimum number of characters that a user's password must contain to some other number.

A: Pluggable Authentication Modules (PAM) are an integral part of the authentication mechanism for the Solaris. PAM provides system administrators with the ability and flexibility to choose any authentication service available on a system to perform end-user authentication.

By using PAM, applications can perform authentication regardless of what authentication method is defined by the system administrator for the given client.

PAM enables system administrators to deploy the appropriate authentication mechanism for each service throughout the network. System administrators can also select one or multiple authentication technologies without modifying applications or utilities. PAM insulates application developers from evolutionary improvements to authentication technologies, while at the same time allowing deployed applications to use those improvements.

PAM employs run-time pluggable modules to provide authentication for system entry services.

E: The Simple Authentication and Security Layer (SASL) is a method for adding authentication support to connection-based protocols.

Simple Authentication and Security Layer (SASL) is a framework for authentication and data security in Internet protocols. It decouples authentication mechanisms from application protocols, in theory allowing any authentication mechanism supported by SASL to be used in any application protocol that uses SASL. Authentication mechanisms can also support proxy authorization, a facility allowing one user to assume the identity of another. They can also provide a data security layer offering data integrity and data confidentiality services. DIGEST-MD5 provides an example of mechanisms which can provide a data-security layer. Application protocols that support SASL typically also support Transport Layer Security (TLS) to complement the services offered by SASL.

If you want to create a backup of an existing boot environment, for example, prior to modifying the original boot environment, you can use the beadm command to create and mount a new boot environment that is a clone of your active boot environment. This clone is listed as an alternate boot environment in the GRUB menu for x86 systems or in the boot menu for SPARC systems.

When you clone a boot environment by using the beadm create command, all supported zones in that boot environment are copied into the new boot environment.

How to Create a Boot Environment

1. Become the root role.

2. Create the boot environment.

# beadm create BeName

BeName is a variable for the name of the new boot environment. This new boot environment is inactive.

3. (Optional) Use the beadm mount command to mount the new boot environment.

# beadm mount BeName mount-point

Note: If the directory for the mount point does not exist, the beadm utility creates the directory, then mounts the boot environment on that directory.

If the boot environment is already mounted, the beadm mount command fails and does not remount the boot environment at the newly specified location.

4. (Optional) Activate the boot environment.

# beadm activate BeName

BeName is a variable for the name of the boot environment to be activated.

On reboot, the newly active boot environment is displayed as the default selection in the x86 GRUB menu or the SPARC boot menu.
