The total size for the Active Directory cache is 20MB. Here's a quick calculation showing how the cache memory is utilized: | Section |
|---|
| Column |
|---|
| Number of Records to cache | 100,000 |
|---|
Number of Attributes per record | 4 |
|---|
Number of bytes per attribute | 50 |
|---|
Total cache size | 100,000 * 4 * 50 = 20MB (approx) |

|
|
Note: The maximum cache size is 25MB
The database pointer information consumes a small portion of the memory, thus the cache capacity will be slightly less than calculation above. |
