[Evolution] Evolution LDAP Size Limitations

[Joe <scubabuzz yahoo com>]

I am using Evolution for email at work.  I have it set up to use EWS and 
look up addresses using the GAL.  We use a separate LDAP server for 
storing user certificates.  There are thousands of user certs on the 
LDAP server and Evolution will find the correct cert if the user is 
within the first group of entries the LDAP server returns but the server 
is limited in it's return size limit so if the user is not within that 
size limit Evolution can't find the cert.

I have tried a similar setup using Thuderbird and it finds the user 
certs fine.  I believe Thunderbird uses LDAP paging so it does not hit 
the limit of the server returns but instead pages through the returns 
until the cert is found.  I saw a post from years ago talking about this 
and I was wondering if this was planned for Evolution in a future 
release.  I know it doesn't work on Evolution 3.36 included with Ubuntu 
20.04.

I have tried a lot of different search filters but nothing returns the 
certificate being searched for.  If I bring up the address book and 
search the LDAP server for the user it does return a match and I can see 
in the 3.36 version that the search filter being sent is (| 
(mail=<emailaddress>) (userCerttificate=*)) when I do not set a search 
filter and when I do this default filter is still being included in the 
search so I wonder if this shouldn't be & instead of | for the default 
filter.

Any ideas on how to get this working?
