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, [email protected], 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 the Kerberos Requirements.

Note that when this class or any other Kerberos-related class is initially loaded and initialized, it may read and cache the default realm from the Kerberos configuration file or via the java.security.krb5.realm system property (the value will be empty if no default realm is specified), such that any subsequent calls to set or change the default realm by setting the java.security.krb5.realm system property may be ignored.

Additionally, if a security manager is installed, a ServicePermission must be granted and the service principal of the permission must minimally be inside the KerberosPrincipal's realm. For example, if the result of new KerberosPrincipal("user") is [email protected], then a ServicePermission with service principal host/[email protected] (and any action) must be granted.

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, [email protected], 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 the Kerberos Requirements.

Note that when this class or any other Kerberos-related class is initially loaded and initialized, it may read and cache the default realm from the Kerberos configuration file or via the java.security.krb5.realm system property (the value will be empty if no default realm is specified), such that any subsequent calls to set or change the default realm by setting the java.security.krb5.realm system property may be ignored.

Additionally, if a security manager is installed, a ServicePermission must be granted and the service principal of the permission must minimally be inside the KerberosPrincipal's realm. For example, if the result of new KerberosPrincipal("user") is [email protected], then a ServicePermission with service principal host/[email protected] (and any action) must be granted.

public String getRealm()

Returns the realm component of this Kerberos principal.

public int hashCode()

Returns a hash code for this KerberosPrincipal. The hash code is defined to be the result of the following calculation:

  hashCode = getName().hashCode();
 

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.

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.

public int getNameType()

Returns the name type of the KerberosPrincipal. Valid name types are specified in Section 6.2 of RFC4120.

public String toString()

Returns an informative textual representation of this KerberosPrincipal.
