A LDIF file is a text file so all of the lines in the file could be read in using the Delimited File node, e.g. by setting the FieldDelimiter parameter to a character that will not appear in the LDIF data (e.g. \x07 = ASCII 'BEL') and the RecordDelimiter to match the file format (UNIX/Windows).
However, LAE does not provide any built-in logic to implent the parsing of the content of the file - it would be necessary to build custom logic to implement a parser. The LDIF specification is here and there are some examples of LDIF file contents here.
So, the files can be read but I would not say that it is easy to leverage the contents of the files.
