    • Constructor Detail

      • KerberosPrincipal

        public KerberosPrincipal(String name)
        Constructs a KerberosPrincipal from the provided string input. The name type for this principal defaults to KRB_NT_PRINCIPAL This string is assumed to contain a name in the format that is specified in Section 2.1.1. (Kerberos Principal Name Form) of RFC 1964 (for example, duke@FOO.COM, where duke represents a principal, and FOO.COM represents a realm).

        If the input name does not contain a realm, the default realm is used. The default realm can be specified either in a Kerberos configuration file or via the java.security.krb5.realm system property. For more information, Kerberos Requirements

        Parameters:
        name - the principal name
        Throws:
        IllegalArgumentException - if name is improperly formatted, if name is null, or if name does not contain the realm to use and the default realm is not specified in either a Kerberos configuration file or via the java.security.krb5.realm system property.
      • KerberosPrincipal

        public KerberosPrincipal(String name,
                                 int nameType)
        Constructs a KerberosPrincipal from the provided string and name type input. The string is assumed to contain a name in the format that is specified in Section 2.1 (Mandatory Name Forms) of RFC 1964. Valid name types are specified in Section 6.2 (Principal Names) of RFC 4120. The input name must be consistent with the provided name type. (for example, duke@FOO.COM, is a valid input string for the name type, KRB_NT_PRINCIPAL where duke represents a principal, and FOO.COM represents a realm).

        If the input name does not contain a realm, the default realm is used. The default realm can be specified either in a Kerberos configuration file or via the java.security.krb5.realm system property. For more information, see Kerberos Requirements.

        Parameters:
        name - the principal name
        nameType - the name type of the principal
        Throws:
        IllegalArgumentException - if name is improperly formatted, if name is null, if the nameType is not supported, or if name does not contain the realm to use and the default realm is not specified in either a Kerberos configuration file or via the java.security.krb5.realm system property.
    • Method Detail

      • getRealm

        public String getRealm()
        Returns the realm component of this Kerberos principal.
        Returns:
        the realm component of this Kerberos principal.
      • equals

        public boolean equals(Object other)
        Compares the specified Object with this Principal for equality. Returns true if the given object is also a KerberosPrincipal and the two KerberosPrincipal instances are equivalent. More formally two KerberosPrincipal instances are equal if the values returned by getName() are equal.
        Specified by:
        equals in interface Principal
        Overrides:
        equals in class Object
        Parameters:
        other - the Object to compare to
        Returns:
        true if the Object passed in represents the same principal as this one, false otherwise.
        See Also:
        Object.hashCode(), HashMap
      • getName

        public String getName()
        The returned string corresponds to the single-string representation of a Kerberos Principal name as specified in Section 2.1 of RFC 1964.
        Specified by:
        getName in interface Principal
        Returns:
        the principal name.
      • getNameType

        public int getNameType()
        Returns the name type of the KerberosPrincipal. Valid name types are specified in Section 6.2 of RFC4120.
        Returns:
        the name type.
      • toString

        public String toString()
        Description copied from class: Object
        Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

        The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

         getClass().getName() + '@' + Integer.toHexString(hashCode())
         
        Specified by:
        toString in interface Principal
        Overrides:
        toString in class Object
        Returns:
        a string representation of the object.
