Time limit is not explicitly set and according to OpenLDAP manual, the
default is 3600 seconds.
I also tried setting soft and hard size limits (size.soft=200
size.hard=none), to see if it would help, but it didn't. Instead, this
weird error appeared:

The PHP max_execution_time was still set to 300 - where did it get the
30 seconds limit!?
Anyway, I then changed PHP max_execution_time to '0', which should stand
for 'unlimited' and tried the tree view again:

Again - where did it get hte 120 seconds time limit?
I then changed OpenLDAP loggin to 'stats', so I could see what searches
it does. First it does a general search with '
base="ou=People,dc=my,dc=org" scope=1 deref=0 filter="(objectClass=*)"
', ' SRCH attr=dn'.
Then it does a search with ' base="DN" scope=0 deref=0
filter="(&(objectClass=*))" ', ' SRCH attr=* + ' for every DN it found
before (that's about 25000 DN's).
Obviously, this would take some time, but when I try to replicate that
in a Bash script using 'ldapsearch' and redirecting results to a file,
the whole thing takes 58 seconds with logging turned off and 90 seconds
with logging turned on.
I used this bash script for testing, if anyone's interested:
