Performing User-Related Administration

The Users page in the ARM allows the ARM operator to:

Add users to the ARM (see Adding a User Not Listed in an AD to the ARM)
Incorporate users into the ARM from a File Repository (see Incorporating Users into the ARM from a File Repository)
Add Users Groups to the ARM (see Adding Users Groups to the ARM)
Determining the total number of users (see Determining Total Users Count
Exporting ARM users to csv (see Exporting ARM Users to CSV File)
Add an LDAP Server to the ARM (see Adding LDAP Server to ARM)
Add an Azure AD Server to the ARM (see Azure AD as a Source for Users in the ARM)
Add a Property Dictionary to the ARM (see Adding a Property Dictionary to the ARM)

The ARM supports up to four million users. They can be inserted from different sources:

File Repositories (typically the most common source for a high number of users – more than 1 million)
Multiple Active Directories (LDAPs) – up to 1 million users per LDAP
Local users

All generic ARM features related to user management are also supported for high numbers of users though some actions like filtering, search, users group creation, users export to csv file, etc., can take longer to perform.

By default, the ARM supports up to 1 million users. To purchase a license for an extended number of users, operators should contact AudioCodes Support.

An operator who manages more than 1 million users will have to deploy ARM Routers with extended memory – 16 GB (instead of the standard 8 GB). High numbers of users requires more memory for using ARM Routers maps for real-time user-based routing.
The ARM Routers memory extension should be applied at a VM level prior to applying a Feature Key with an extended number of users.
In the case of adding a new ARM Router to the ARM with an extended number of users (more than 1 million), the Router’s VM should have 16 GB memory.

If the Origin (source) of users is LDAP Server/Active Directory and the operator manages more than 1 million users, the users should be divided among several LDAP servers where each LDAP hosts up to 1 million users.
