Directory URI Case Sensitivity Configuration Parameter

D.

Cisco Unified Communications Manager supports the following formats in the user portion of a directory URI (the portion before the @ symbol): -> Accepted characters are a-z, A-Z, 0-9, !, $, %, &, *, _, +, ~, -, =, \, ?, \, , ,, ., /

-> The user portion has a maximum length of 47 characters.

-> The user portion accepts percent encoding from %2[0-9A-F] through %7[0-9A-F]

For some accepted characters, Unified CM automatically applies percent encoding.

See below for more information on percent encoding.

The default value is - -> The user portion is case-sensitive or case-insensitive depending on the value of the URI Lookup Policy enterprise parameter.

case-sensitive.

The correct answer to this question is B. URI Lookup Policy in Cisco CallManager Service Parameter.

A directory URI is a Uniform Resource Identifier that identifies a user in a directory. It consists of the user portion and the domain portion. The user portion can contain alphanumeric characters, hyphens, and periods.

In Cisco Unified Communications Manager 9.1 or later, the case sensitivity of the user portion of a directory URI is determined by the URI Lookup Policy configuration parameter. This parameter can be set in the Cisco CallManager service parameters.

URI Lookup Policy determines how Cisco Unified Communications Manager searches for directory URIs in the LDAP directory. There are three possible values for this parameter:

• Case Insensitive: Cisco Unified Communications Manager ignores the case of the user portion of the directory URI when searching the directory.
• Case Sensitive: Cisco Unified Communications Manager performs a case-sensitive search for the user portion of the directory URI.
• Use System Default: Cisco Unified Communications Manager uses the system-wide default setting for URI Lookup Policy.

By default, the URI Lookup Policy is set to Use System Default, which means that the system-wide default setting is used. The system-wide default setting can be set in the Enterprise Parameters configuration parameter, but it does not directly control the case sensitivity of the user portion of the directory URI.

In summary, the configuration parameter that defines whether or not the user portion of a directory URI is case sensitive on Cisco Unified Communications Manager 9.1 or later is the URI Lookup Policy configuration parameter, which can be set in the Cisco CallManager service parameters.
