Abstract
Abstract A system wide sign-on capability in a distributed computing environment (DCE) is provided. Acquired distributed computing environment credentials are usable by any process/window on a desktop. DCE logon application programming interfaces create and recognize the presence of a credentials cache capable of being used by DCE processes in the system. System wide logon occurs whenever the logon API is invoked with the environment variable set. This API is called as a result of the system logon option having been selected. The API updates a global variable with the name of the credentials cache. A process variable is set to the global value by initialization logic for all subsequently invoked applications. As a result, any calls made by these application will acquire the credentials identified by the variable.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
127 words
A method for locating a user's credentials for using a local computer system in a distributed computing environment, comprising the steps of: providing an operating system within said local computer system having a plurality of applications; starting a selected one of said applications by said user at said local computer system; determining in said selected application whether a pointer to the user's credentials exists at the local computer system before logging onto said distributed computing environment, if so, using the user's credentials; if not, determining in said selected application whether a default set of credentials exists at the local computer system, if so, using the default set of user credentials; and if not, using a set of credentials for the local computer system in said selected application.
Claim 2
Independent Claim
127 words
A method for locating a user's credentials for using a local computer system in a distributed computing environment, comprising the steps of: providing an operating system within said local computer system having a plurality of applications; starting a selected one of said applications by said user at said local computer system; determining in said selected application whether a pointer to the user's credentials exists at the local computer system before logging onto said distributed computing environment, if so, using the user's credentials; if not, determining in said selected application whether a default set of credentials exists at the local computer system, if so, using the default set of user credentials; and if not, using a set of credentials for the local computer system in said selected application.
Claim 3
Dependent Claim
55 words
The method of claim 1, further comprising the steps of: determining whether a process in said selected application associated with said operating system on said local computer system logged onto said distributed computing environment can use the default set of user credentials; and if not, using the set of credentials for the local computer system.
Claim 4
Independent Claim
127 words
An apparatus for locating a user's credentials for use in a local computer system in a distributed computing environment, comprising: providing an operating system in said local computer system having a plurality of applications; starting a selected one of said applications by said user at said local computer system; means for determining in said selected application whether a pointer to the user's credentials exists at the local computer system before logging onto said distributed computing environment, if so, using the user's credentials; if not, means for determining in said selected application whether a default set of credentials exists at the local computer system, if so, using the default set of user credentials; and if not, means for using a set of credentials for the local computer system.
Claim 5
Independent Claim
127 words
An apparatus for locating a user's credentials for use in a local computer system in a distributed computing environment, comprising: providing an operating system in said local computer system having a plurality of applications; starting a selected one of said applications by said user at said local computer system; means for determining in said selected application whether a pointer to the user's credentials exists at the local computer system before logging onto said distributed computing environment, if so, using the user's credentials; if not, means for determining in said selected application whether a default set of credentials exists at the local computer system, if so, using the default set of user credentials; and if not, means for using a set of credentials for the local computer system.
Claim 6
Dependent Claim
36 words
The apparatus of claim 3, further comprising: means for determining whether a process can use the default set of user credentials; and if not, means for using the set of credentials for the local computer system.
Claim 7
Dependent Claim
174 words
A computer program product having a computer readable medium having computer program logic recorded thereon for locating a user's credentials using a local computer system in a distributed computing environment, comprising: computer readable program code means for providing an operating system in said local computer system having a plurality of applications; computer readable program code means for starting a selected one of said applications by said user at said local computer system; computer readable program code means for determining in said selected application whether a pointer to the user's credentials exists at the local computer system before logging onto said distributed computing environment, if so, computer readable program code means for using the user's credentials; if not, computer readable program code means for determining in said selected application whether a default set of credentials exists at the local computer system, if so, computer readable program code means for using the default set of user credentials; and if not, computer readable program code means for using a set of credentials for the local computer system.
Claim 8
Dependent Claim
174 words
A computer program product having a computer readable medium having computer program logic recorded thereon for locating a user's credentials using a local computer system in a distributed computing environment, comprising: computer readable program code means for providing an operating system in said local computer system having a plurality of applications; computer readable program code means for starting a selected one of said applications by said user at said local computer system; computer readable program code means for determining in said selected application whether a pointer to the user's credentials exists at the local computer system before logging onto said distributed computing environment, if so, computer readable program code means for using the user's credentials; if not, computer readable program code means for determining in said selected application whether a default set of credentials exists at the local computer system, if so, computer readable program code means for using the default set of user credentials; and if not, computer readable program code means for using a set of credentials for the local computer system.
Claim 9
Dependent Claim
