This means you're either hitting the lookthroughlimit and/or the 
idlistscanlimit.

The idlistscanlimit is described here - 
https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Directory_Server/9.0/html/Configuration_Command_and_File_Reference/Database_Plug_in_Attributes.html#nsslapd_idlistscanlimit

I suggest changing the value to be 2 times as large as the number of 
entries in your database, just to be safe:

ldapmodify -x -D "cn=directory manager" -W <<EOF
dn: cn=config,cn=ldbm database,cn=plugins,cn=config
changetype: modify
replace: nsslapd-idlistscanlimit
nsslapd-idlistscanlimit: a big number
EOF

If you still have a problem, it means ipa is doing an unindexed search, 
and you will have to increase the lookthroughlimit for the ipa admin 
user.  I'm not sure how/where ipa does that.  You can set the global 
limit for all users like this:

ldapmodify -x -D "cn=directory manager" -W <<EOF
dn: cn=config
changetype: modify
replace: nsslapd-lookthroughlimit
nsslapd-lookthroughlimit: a big number
EOF

In case you are wondering what all of this gibberish is

https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Directory_Server/9.0/html/Administration_Guide/Managing_Indexes.html#About_Indexes-Overview_of_the_Searching_Algorithm

When the directory server cannot load the IDs of the search results into 
an ID list, either due to hitting the idlistscanlimit, or the search is 
unindexed (and therefore there is no index to load the ID list), the 
server must fall back to searching through every entry in the database.  
It will only look through nsslapd-lookthroughlimit number of entries 
before giving up and returning err=11.

Can you take a look at the directory server access log at 
/var/log/dirsrv/slapd-INST/access and look for the corresponding SRCH 
operation and the RESULT of that search operation and please post it?
