8.3. Tuning the maximum buffer size for the ipa-extdom plugin on IdM servers
IdM clients cannot receive information about users and groups from Active Directory (AD) directly, so IdM servers use the ipa-extdom plugin to receive information about AD users and groups, and that information is forwarded to the requesting client.
You can tune the maximum buffer size for the ipa-extdom plugin, which adjusts the size of the buffer where SSSD can store the data it receives. If the buffer is too small, SSSD returns an ERANGE error and the plug-in retries the request with a larger buffer. The default buffer size is 134217728 bytes (128 MB).
The following example adjusts the maximum buffer size to 256 MB (268435456 bytes).
