Defining LDAP Subscription ID Filters

You can configure multiple search filters per data source. For example, if a data source supports searching by MSISDN and IMSI, you can define multiple MSISDN and IMSI filters.
Note: Best practice recommends to priority order filtered data sources higher than unfiltered ones. See Ordering Data Source Priority for details on re-ordering data sources.
The APN search filter supports regular expressions and uses these patterns:
  • Wild Card: Pattern.*
  • Equal to: Pattern
  • Not Equal to: ^(?!.*Pattern).*$
These rules are followed when using the search filters:
  • If only subscription ID filters exist, if at least one subscription ID filter is matched, the result is matched.
  • If only APN filters exist, if at least one APN filter is matched, the result is matched.
  • If APN filters and subscription ID filters exist, if at least one subscription ID filter and one APN filter are matched, the result is matched.

To define LDAP Subscription ID search filters:

  1. Click Search Filters tab.
  2. In the Subscription ID section, select the Key Type from the list:
    • User Name (default)

      User name (account ID)

    • NAI

      Network address ID

    • E.164 (MSISDN)

      E.164 phone number

    • IMSI

      International Mobile Subscriber Identity

    • IP Address

      IP address

  3. Enter a regular expression to use to filter the search results.
    For example:
    • 508.*

      Matches numbers beginning with 508

    • ".*@example.com"

      Matches strings ending with @example.com

    • .*

      Matches any input string

  4. Click Add.

    The expression appears in the list of search filters.

  5. Click Save or proceed with Selecting LDAP Associated Data Sources.
