Zimbra 8.7 and later
Adjust these settings in LDAP
- zimbraShortTermAllEffectiveRightsCacheExpiration (default: 50s)
- zimbraShortTermAllEffectiveRightsCacheSize (default: 128)
- zimbraShortTermGranteeCacheExpiration (default: 50s)
- zimbraShortTermGranteeCacheSize (default: 128)
Zimbra 8.6 patch 2 and later patch levels
Configure these LC keys:
- short_term_all_effective_rights_cache_expiration (default: 50000)
- short_term_all_effective_rights_cache_size (default: 128)
- short_term_grantee_cache_expiration (default: 50000)

LDAP key descriptions
zimbraShortTermAllEffectiveRightsCacheSize
Maximum number of entries in the short term All Effective Rights cache.
This cache can improve performance by avoiding recomputing All Effective Rights of named entries like accounts frequently in a short period of time.
Can disable the cache be specifying a value of 0
The default value is 128
zimbraShortTermAllEffectiveRightsCacheExpiration
Maximum time an entry in the short term All Effective Rights cache will be regarded as valid.
If value is 0, the cache is disabled.
The cache is particularly useful when significant use is made of delegated administration.
All Effective Rights are computations of the rights that named entries like accounts have - although when used, they are checked separately.
The longer the value of this setting is, the more stale the view of the details is likely to be. For this reason, the maximum accepted value is 30m. Larger values will be treated as being 30m
The default value is 50s
zimbraShortTermGranteeCacheSize
Maximum number of entries in the short term Grantee cache.
This cache can improve performance by avoiding recomputing details frequently in a short period of time, for instance for each entry in search results.
Can disable the cache be specifying a value of 0
The default value is 128
zimbraShortTermGranteeCacheExpiration
Maximum time an entry in the Grantee cache will be regarded as valid.
If value is 0, the cache is disabled.
The cache is particularly useful when significant use is made of delegated administration.
Grantees objects provide a view of what rights a grantee has - although those are checked separately.
The longer the value of this setting is, the more stale the view of the details is likely to be. For this reason, the maximum accepted value is 30m. Larger values will be treated as being 30m
The default value is 50s
