I have a problem with adding filter for attribute, which exist not in all members of organization unit. I set filter like this^ (status=Active) But this property doesn't exist in half of members and server returns "unwilling to execute 53 error". I wonder how should I rewrite this filter query to make it work only for objects with this attribute? Thanks

LDAP filters consist of one or more criteria. If one than more criterion exist in one filter definition, they can be concatenated by logical AND or OR operators. The logical operators are always placed in front of the operands (i.e. the criteria). This is the so-called 'Polish Notation'.
There is no way to escape value based on the final filter because the start and end position cannot be identified anymore. To resolve this ambiguity and filter injection issue, the input values must be escaped while building the filter, not afterwards.
LDAP search filters are used in 2 places in the Directory Synchronization Client: Selecting which objects are returned when browsing for the search base. Identifying which objects in your directory are examined, for example email address attributes or user attributes.
status attribute, use a present filter, for example, (status=*).status attribute, negate the present filter: (!(status=*)).status attribute is indexed for equality and presence. If do not have access to this information, check with the LDAP administrators in the appropriate organization.
