Users Overview


Each user entry in the SBR Carrier database identifies one method by which the server can authenticate a specific user. Native user entries require you to enter the username and password into the SBR Carrier database. For all other types of user entry, the server relies on another database to confirm the user password.

You can add a UNIX user entry to provide authentication for a specific user defined on the Solaris or Linux server. For more flexibility, you can add a UNIX group to provide authentication for all users that belong to a specific group defined on the server.


You can populate the user database for SBR Carrier by entering information using the Web GUI or by importing data from other servers. For more information about importing user information, see Importing and Exporting Data.

Allowed Access Hours

Allowed Access Hours

The user’s allowed access hours can be specified by adding the Funk-Allowed-Access-Hours attribute to the user’s check list.

Funk-Allowed-Access-Hours is a variable-length string that identifies time periods in a 7-day week of 24-hour days. This string consists of one or more day specifiers (each of which can list one or more days or ranges of days) followed by one or more ranges of 24-hour times, in minutes.

The following is a sample Funk-Allowed-Access-Hours attribute value:

The syntax rules for Funk-Allowed-Access-Hours are as follows:

  • Time ranges can be inclusive (1000–1100 allows access only between 10 a.m. and 11 a.m.) or exclusive (1100–1000 allows access any time except between 10 a.m. and 11 a.m.).

  • Day specifiers, and ranges of days and times can be separated by commas or spaces; ranges of days or times are indicated by hyphens (m–w or 0239–1459).

  • Days can be specified by the minimum number of case-insensitive letters necessary to distinguish them (Su, M, Tu, W, Th, F, Sa) and can wrap around the end of the week (Sa-Su).

  • At least one time period is required for each day; that is, each day, list, or range of days must be followed by one or more ranges of times.

  • Times are specified using four digits, with leading zeroes where needed (0001 for 12:01 a.m., 0630 for 6:30 a.m., and so forth).

When assigned to a user’s check list, the Funk-Allowed-Access-Hours value allows the user access during the following time periods:

  • 1 a.m. to 2 p.m. and 11:00 p.m. to midnight, Monday through Wednesday

  • 5:30 a.m. to 3:00 p.m. Monday, Tuesday, Thursday, and Friday

  • Any time Saturday or Sunday

The total access times Monday are 1 a.m. to 3:00 p.m. and 11:00 p.m. to midnight.

If the user attempts access on Sunday at 11:30 p.m., access would be allowed and a Session-Timeout attribute specifying a value of 1800 seconds (30 minutes, until midnight Sunday, when the access period ends) would be returned. However, if the user’s return list includes a Session-Timeout with a value less than 1800, this lesser value would be returned.
