I am migrating an openLDAP tree into ipa, and when I run ipa

migration aborts after roughly 36 seconds with:
ipa: ERROR: cannot connect to 'ldap://10.x.x.x:389’:
It has transferred 9762 records, but seems to hit a timeout that
causes it to stop.
I’ve run it in debug mode, which only provides this:
ipa: DEBUG: Starting external process
ipa: DEBUG: args=keyctl pupdate 774698354
ipa: DEBUG: Process finished, return code=0

ipa: DEBUG: Destroyed connection context.xmlclient
ipa: ERROR: cannot connect to 'ldap://10.x.x.x:389':
Initially, it had transferred 2000 records and stopped, until I set
nsslapd-sizelimit in cn=config:
nsslapd-sizelimit: 20000
I then re-ran the migration a dozen times, each time it would
transfer more
records, but would always time out at around the 36 second mark. Now
that I’m
at 9762 records, it seems to have reached a peak.
I suspect this is another tunable, but haven’t been able to find it, any
document that mentions it, or anyone else hitting this issue.
RHEL 7.0 server
idM ipa-server-3.3.3-28
source is RHEL 6.5 running openldap-2.4.23-34
command used to migrate:
ipa migrate-ds --continue
--bind-dn="uid=me,ou=people,ou=foo,dc=example,dc=com"
--base-dn="ou=foo,dc=example,dc=com" ldap://10.x.x.x:389

Ludwig, do you know? I am just thinking it may be also caused by some
form of timelimit, as mentioned in
https://access.redhat.com/documentation/en-US/Red_Hat_Directory_Server/8.2/html/Administration_Guide/User_Account_Management-Setting_Resource_Limits_Based_on_the_Bind_DN.html
(those apply both for bind DNs and global cn=config). Maybe
nsslapd-timelimit could be increased? Although I saw the default is
3600, I assume it means 1 hour, i.e. not being the root cause.
we need the access and error logs from DS, if it is a DS limit it should
be seen in the err code.
Could it be that migrate-ds has it's own limit waiting for a repsponse
from DS ?
