decoding attrs error

["Angel L. Mateo" <amateo@um.es>]

Hello,

	I have a web application that doesn't work with openldap 2.4.21. The 
same application is working with an old openldap 2.3.30.

	The problem I have is that for some reason this application performs a 
search with an undefined filter, the error I get in normal run is:

Dec 12 13:26:47 canis21 slapd[29241]: get_filter: unknown filter type=48

	In the older slapd, log is:

Dec 12 03:59:14 canis5 slapd[16830]: conn=3220865 op=3 SRCH 
base="dc=unidades,dc=vistas,dc=um,dc=es" scope=1 deref=0 
filter="(?=undefined)"
Dec 12 03:59:14 canis5 slapd[16830]: conn=3220865 op=3 SEARCH RESULT 
tag=101 err=0 nentries=0 text=

	If I run slapd in debug mode, I get:
