Entries can come from any of the sources specified in the \fBnsswitch.conf\fR(4) file. .sp .LP The \fBgetauthattr()\fR function enumerates \fBauth_attr\fR entries. The \fBgetauthnam()\fR function searches for an \fBauth_attr\fR entry with a given authorization name \fIname\fR. Successive calls to these functions return either successive \fBauth_attr\fR entries or \fINULL\fR. .sp .LP Th internal representation of an \fBauth_attr\fR entry is an \fBauthattr_t\fR structure defined in <\fBauth_attr.h\fR> with the following members: .sp .in +2 .nf char *name; /* name of the authorization */ char *res1; /* reserved for future use */ char *res2; /* reserved for future use */ char *short_desc; /* short description */ char *long_desc; /* long description */ kva_t *attr; /* array of key-value pair attributes */ .fi .in -2 .sp .LP The \fBsetauthattr()\fR function "rewinds" to the beginning of the enumeration of \fBauth_attr\fR entries. Calls to \fBgetauthnam()\fR can leave the enumeration in an indeterminate state. Therefore, \fBsetauthattr()\fR should be called before the first call to \fBgetauthattr()\fR. .sp .LP The \fBendauthattr()\fR function may be called to indicate that \fBauth_attr\fR processing is complete; the system may then close any open \fBauth_attr\fR file, deallocate storage, and so forth. .sp .LP The \fBchkauthattr()\fR function verifies whether or not a user has a given authorization. It first reads the \fBAUTHS_GRANTED\fR key in the \fB/etc/security/policy.conf\fR file and returns 1 if it finds a match for the given authorization. If \fBchkauthattr()\fR does not find a match and the \fIusername\fR is the name of the "console user", defined as the owner of \fB/dev/console\fR, it first reads the \fBCONSOLE_USER\fR key in \fB/etc/security/policy.conf\fR and returns 1 if the given authorization is in any of the profiles specified in the \fBCONSOLE_USER\fR keyword, then reads the \fBPROFS_GRANTED\fR key in \fB/etc/security/policy.conf\fR and returns 1 if the given authorization is in any profiles specified with the \fBPROFS_GRANTED\fR keyword. If a match is not found from the default authorizations and default profiles, \fBchkauthattr()\fR reads the \fBuser_attr\fR(4) database. If it does not find a match in \fBuser_attr\fR, it reads the \fBprof_attr\fR(4) database, using the list of profiles assigned to the user, and checks if any of the profiles assigned to the user has the given authorization. The \fBchkauthattr()\fR function returns 0 if it does not find a match in any of the three sources or if the user does not exist. .sp .LP A user is considered to have been assigned an authorization if either of the following are true: .RS +4 .TP .ie t \(bu .el o The authorization name matches exactly any authorization assigned in the \fBuser_attr\fR or \fBprof_attr\fR databases (authorization names are case-sensitive). .RE .RS +4 .TP .ie t \(bu .el o The authorization name suffix is not the key word \fBgrant\fR and the authorization name matches any authorization up to the asterisk (*) character assigned in the \fBuser_attr\fR or \fBprof_attr\fR databases. .RE .sp .LP The examples in the following table illustrate the conditions under which a user is assigned an authorization. .sp .sp .TS box; c | c | c c | c | c . \f(CW/etc/security/policy.conf\fR or Is user _ \fBAuthorization name\fR \fBuser_attr\fR or \fB\fR \fBprof_attr\fR entry authorized? _ solaris.printer.postscript solaris.printer.postscript Yes solaris.printer.postscript solaris.printer.* Yes solaris.printer.grant solaris.printer.* No .TE .sp .LP The \fBfree_authattr()\fR function releases memory allocated by the \fBgetauthnam()\fR and \fBgetauthattr()\fR functions. .SH RETURN VALUES .sp .LP The \fBgetauthattr()\fR function returns a pointer to an \fBauthattr_t\fR if it successfully enumerates an entry; otherwise it returns \fINULL\fR, indicating the end of the enumeration. .sp .LP The \fBgetauthnam()\fR function returns a pointer to an \fBauthattr_t\fR if it successfully locates the requested entry; otherwise it returns \fINULL\fR. .sp .LP The \fBchkauthattr()\fR function returns 1 if the user is authorized and 0 if the user does not exist or is not authorized. .SH USAGE .sp .LP The \fBgetauthattr()\fR and \fBgetauthnam()\fR functions both allocate memory for the pointers they return. This memory should be deallocated with the \fBfree_authattr()\fR call. .sp .LP Individual attributes in the \fBattr\fR structure can be referred to by calling the \fBkva_match\fR(3SECDB) function. .SH WARNINGS .sp .LP Because the list of legal keys is likely to expand, code must be written to ignore unknown key-value pairs without error. .SH FILES .sp .ne 2 .na \fB\fB/etc/nsswitch.conf\fR\fR .ad .RS 29n configuration file lookup information for the name server switch .RE .sp .ne 2 .na \fB\fB/etc/user_attr\fR\fR .ad .RS 29n extended user attributes .RE .sp .ne 2 .na \fB\fB/etc/security/auth_attr\fR\fR .ad .RS 29n authorization attributes .RE .sp .ne 2 .na \fB\fB/etc/security/policy.conf\fR\fR .ad .RS 29n policy definitions .RE .sp .ne 2 .na \fB\fB/etc/security/prof_attr\fR\fR .ad .RS 29n profile information .RE .SH ATTRIBUTES .sp .LP See \fBattributes\fR(5) for descriptions of the following attributes: .sp .sp .TS box; c | c l | l .
