How do I increase the number of Unix ID’s allocated to Scalix?
From Scalix Wiki
Each Scalix mailbox added requires a Unix/Linux ID. In cases where more than 1000 users exist on the Scalix server, increase the pool or add additional pools to draw IDs from.
1) To first display the pool, run the following command (which is also the default amount).
# omadmidp -u Start of block: 64534 Range of block: 1000 Used in block: 7
2) Now increase the pools, in this example, we’ll add 1000 ids.
# omadmidp -a -s 66000 -n 1000 omadmidp: Unix IDs pool 66000..66999 successfully added
3) Now review what has been allocated.
# omadmidp -u Start of block: 64534 Range of block: 1000 Used in block: 7 Start of block: 66000 Range of block: 1000 Used in block: 0
