851. Introduction (non-normative)

86 1.1. Concepts

87SPML Version 2 (SPMLv2) defines a core protocol [SPMLv2] over which different data models can 88be used to define the actual provisioning data. The combination of a data model with the SPML 89core specification is referred to as a profile. The use of SPML requires that a specific profile is used, 90although the choice of which profile is used to negatioted out-of-band by the participating parties. 91This document describes the use of the SAML protocol as a data model for SPML based 92provisioning. This profile is optional.

93 1.1.1. SAML Protocol 94The SAML 2.0 protocol [SAMLv2???] defines the syntax and processing semantics of 95assertions made about a subject by a system entity. ***Say some more here??

96 1.2. Terminology

97Within this document: 98- The term “requestor” always refers to a Requesting Authority (RA). 99- The term “provider” always refers to a Provisioning Service Provider (PSP). 100- The term “target” always refers to a Provisioning Service Target (PST). 101- The term “object” (unless otherwise qualified) refers to a Provisioning Service Object (PSO). 102- The term “client” (unless otherwise qualified) refers to a Requesting Authority (RA). 103- The term “server” (unless otherwise qualified) refers to a Provisioning Service Provider (PSP).

1042. Notation

105This specification contains schema conforming to W3C XML Schema and normative text to 106describe the syntax and semantics of XML-encoded policy statements. 107The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", 108"SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this specification are to be 109interpreted as described in IETF RFC 2119 [RFC2119] 110 "they MUST only be used where it is actually required for interoperation or to limit 111 behavior which has potential for causing harm (e.g., limiting retransmissions)" 112These keywords are thus capitalized when used to unambiguously specify requirements over 113protocol and application features and behavior that affect the interoperability and security of 114implementations. When these words are not capitalized, they are meant in their natural-language 115sense. 116This specification uses the following typographical conventions in text:

117Terms in italic bold-face are intended to have the meaning defined in the Glossary.

118Listings of SPML schemas appear like this.

119 120Example code listings appear like this. 121Conventional XML namespace prefixes are used throughout the listings in this specification to 122stand for their respective namespaces as follows, whether or not a namespace declaration is 123present in the example: 124- The prefix saml: stands for the SAML assertion namespace [SAML]. 125- The prefix ds: stands for the W3C XML Signature namespace [DS]. 126- The prefix xsd: stands for the W3C XML Schema namespace [XS].

1273. Overview (non-normative)

128 3.1. SAML PSOs

129A PSO is represented in this binding by an SAML Attribute Assertion that is associated with a 130target-unique SAML identifier. 131The SAML Attribute Assertions are used to provide identity and attribute data for a Provisioning 132Service Object. The PSO is equivalent to a SAML Subject in this regard.

133 3.1.1. PSO Identifier

134The PSO Identifier may be one of several types of SAML NameID identifiers. However, not every 135identifier specified in SAML is allowed as an identifier for a PSO. The following SAML name 136identifiers are allowed: 137  Unspecified

138 URI: urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified 139 The interpretation of the content of the element is left to individual implementations.

100c759f64cb623dcecd6ce45eff772a26.doc 7/17/2006 11Copyright © OASIS Open 2006. All Rights Reserved. Page 5 of 15 140 141  E-Mail address 142 URI: urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress 143 144 Indicates that the content of the element is in the form of an email address, specifically 145 "addr-spec" as defined in IETF RFC 2822 [RFC 2822] Section 3.4.1. An addr-spec has the 146 form local-part@domain. Note that an addr-spec has no phrase (such as a common name) 147 before it, has no comment (text surrounded in parentheses) after it, and is not surrounded 148 by "<" and ">". 149 150  X509 Subject Name 151 URI: urn:oasis:names:tc:SAML:1.1:nameid-format:X509SubjectName 152 153 Indicates that the content of the element is in the form specified for the contents of the 154 element in the XML Signature Recommendation [XMLSig]. 155 Implementors should note that the XML Signature specification specifies encoding rules for 156 X.509 subject names that differ from the rules given in IETF RFC 2253 [RFC 2253]. 157 158  WindowsDomainQualifiedname 159 URI: urn:oasis:names:tc:SAML:1.1:nameid- 160 format:WindowsDomainQualifiedName 161 162 Indicates that the content of the element is a Windows domain qualified name. A Windows 163 domain qualified user name is a string of the form "DomainName\UserName". The domain 164 name and "\" separator MAY be omitted. 165  Kerberos 166 URI: urn:oasis:names:tc:SAML:2.0:nameid-format:kerberos 167 168 Indicates that the content of the element is in the form of a Kerberos principal name using 169 the format name[/instance]@REALM. The syntax, format and characters allowed for the 170 name, instance, and realm are described in IETF RFC 1510 [RFC 1510]. 171 172Below is an example of a psoID using a SAML X509 NameIdentifier. 173 174 175 cn=John Doe,dc=acme,dc=com 176 177

178 3.1.2. PSO Data

179The PSO Data element contains SAML Attribute Assertions, as defined in [SAML]. Additional data 180may be included via the Open Content Model. 181 182 183 184 [email protected] 185 186 187

189***how to handle schema with SAML?

190 3.3. Core Operations

191 3.3.1. Add Request

192The Add Request creates PSOs. The Add Request must contain a element that contains 193SAML 2.0 elements that define the new PSO. The Add Request may also pass a PSO 194Identifier ( element), a container PSO ID ( element), or a target ID 195( element). If a PSO identifier is not defined in the Add Request, the new PSO Identifier 196must be returned in the Add Response. 197 198 199 200 201 John 202 203 204 Doe 205 206 207 [email protected] 208 209 210

211 3.3.2. Add Response

212The Add Response message will contain the new PSO ID (unless it was specified in the Add 213Request). If the creation of the new PSO resulted in attributes being adding or modified in the new 214PSO, the entire PSO Data should be returned in the response. 215 216 217 cn=John Doe,dc=acme,dc=com 218 219 220 221 John 222 223 224 Doe 225 226 227 [email protected] 228 229 230 John Doe 231 232 233 jdoe 234 235 236

238The Modify Request modifies the specified PSO. The Modify Request must always contain the PSO 239Identifier. ??Modify will always replace *all* existing values for the specified attribute? If a MVA, can 240we specify the original value so we only replace 1? Is this beyond the score here?? 241 242 243 cn=John Doe,dc=acme,dc=com 244 245 246 247 Jane 248 249 250

251 3.3.4. Modify Response

252If the Modify Request causes the PSO ID to change, then the Modify Response must contain the 253new PSO ID. 254 256 257 cn=Jane Doe,dc=acme,dc=com 258 259

260 3.3.5. Delete Request

261The Delete Request deletes a specified PSO. 262 263 264 cn=John Doe,dc=acme,dc=com 265 266

267

268 3.3.6. Lookup Request

269The Lookup Request is used to retrieve the data for a specified PSO. 270 271 272 cn=John Doe,dc=acme,dc=com 273 274

275 3.3.7. Lookup Response

276The Lookup Response contains the retrieved PSO data. 277 279

300 3.4. Search Operations

301If the Search Capability is supported, the SAML search filters and attribute declarations should be 302used to scope the results of the search.

303 3.4.1. Search Request

304The search request can specify SAML filters and attribute declarations. 305***How to handle search base “basePSOID”? What filter mechanism to use? DSML was specifically 306applicable here.. ?? 307 309 310*** example: firstname = John, get email 311 312

3404. Specification (Normative)

341 4.1. Namespaces

342The SAMLv2 Profile uses the SAML 2.0 namespace which is defined as: 343 urn:oasis:names:tc:SAML:2.0 344The specification uses the prefix SAML: to refer to this namespace. 345The SAMLv2 Profile defines some elements that are specific to the profile. The namespace for the 346profile itself is defined as: 347 urn:oasis:names:tc:SPML:2:0:SAML 348The specification uses the prefix spmlSAML: to refer to this namespace.

349 4.2. Core Capability

350 4.2.1. Element

351The element MUST contain zero or many elements.

352 4.2.2. Element

353The element MUST contain zero or many elements. The 354“modificationType” on the MUST be specified.

355 4.2.3. Element

356***

357 4.2.4. Element

358The “entityName” attribute on the element MUST refer only to 359object classes defined in the referenced schema. All attributes on the referenced object classes are 360assumed to be supported. ***How this applies will depend on how we handle object classes in 361SAML??
