-.Os HEIMDAL
-.Sh NAME
-.Nm su
-.Nd substitute user identity
-.Sh SYNOPSIS
-.Nm su
-.Op Fl K | Fl Fl no-kerberos
-.Op Fl f
-.Op Fl l | Fl Fl full
-.Op Fl m
-.Oo Fl i Ar instance \*(Ba Xo
-.Fl Fl instance= Ns Ar instance
-.Xc
-.Oc
-.Oo Fl c Ar command \*(Ba Xo
-.Fl Fl command= Ns Ar command
-.Xc
-.Oc
-.Op Ar login Op Ar "shell arguments"
-.Sh DESCRIPTION
-.Nm su
-will use Kerberos authentication provided that an instance for the
-user wanting to change effective UID is present in a file named
-.Pa .k5login
-in the target user id's home directory
-.Pp
-A special case exists where
-.Ql root Ap s
-.Pa ~/.k5login
-needs to contain an entry for:
-.Ql user Ns / Ns Ao instance Ac Ns @ Ns REALM
-for
-.Nm su
-to succed (where
-.Aq instance
-is
-.Ql root
-unless changed with
-.Fl i ) .
-.Pp
-In the absence of either an entry for current user in said file or
-other problems like missing
-.Ql host/hostname@REALM
-keys in the system's
-keytab, or user typing the wrong password,
-.Nm su
-will fall back to traditional
-.Pa /etc/passwd
-authentication.
-.Pp
-When using
-.Pa /etc/passwd
-authentication,
-.Nm su
-allows
-.Ql root
-access only to members of the group
-.Ql wheel ,
-or to any user (with knowledge of the
-.Ql root
-password) if that group
-does not exist, or has no members.
-.Pp
-The options are as follows:
-.Bl -item -width Ds
-.It
-.Fl K ,
-.Fl Fl no-kerberos
-don't use Kerberos.
-.It
-.Fl f
-don't read .cshrc.
-.It
-.Fl l ,
-.Fl Fl full
-simulate full login.
-.It
-.Fl m
-leave environment unmodified.
-.It
-.Fl i Ar instance ,
-.Fl Fl instance= Ns Ar instance
-root instance to use.
-.It
-.Fl c Ar command ,
-.Fl Fl command= Ns Ar command
-command to execute.
