Description:

 Starting from 2048, the first input line larger than any power of two N
 is truncated to N-1. This results in truncated values in the database.

Thanks for the report. Fixed now in mdb.master

Explanation:

 In the code that resizes the input buffer, fgets() is used.
 fgets(*, n, *) reads a maximum of n-1 characters and 0-terminates
 the string. When the next chunk is read, the '\0' remains in the
 string. Later, strlen() is used and the string is truncated.

Proposed fix:

 A patch against the current OpenLDAP master llllows.
