+.Sh DESCRIPTION
+Getting initial credential ticket for a principal.
+This ins the interface that replaces the deprecated
+.Fa krb5_in_tkt
+and 
+.Fa krb5_in_cred
+interfaces.
+.Pp
+If you only to verify a user and password, consider using
+.Xr krb5_verify_user 3
+instead, since it also verifies that initial credentials with using a
+keytab to make sure the response was from the KDC.
