Hello,

I am running openldap 2.6.3 configured as provider-consumer and I would like to do backup/restore of the database on the provider.

I create a backup on working sladp using command(ends with success, file created):
slapd.exe –T cat –f slapd.conf –l backup.ldif

And then trying to load it using slapd command into a new database(restore):
slapd.exe -T add -f slapd.conf -l backup.ldif -d -1

Command ends with:
.

slapadd: could not parse entry (line=1)

When I look into backup.ldif files I see that there is an '-' in contextCSN timestamp which cause this behaviour:
